The need for medications to prevent stress ulcer among those in the intensive care unit is unclear. As of 2014, the quality of the evidence is poor. It is unclear which agent is best or if prevention is needed at all. Benefit may only occur in those who are not being fed.

Possible agents include antacids, H2-receptor blockers, sucralfate, and proton pump inhibitors (PPIs). Tentative evidence supports that PPIs may be better than H2 blockers.

Concerns with the use of stress ulcer prophylaxis agents include increased rates of pneumonia and "Clostridium difficile" colitis.

The principles of management are the same as for the chronic ulcer. The steps of management are similar as in erosive gastritis.

Endoscopic means of treating stress ulceration may be ineffective and operation required. It is believed that shunting of blood away from the mucosa makes the mucous membrane ischaemic and more susceptible to injury.

Treatment of stress ulceration usually begins with prevention. Careful attention to respiratory status, acid-base balance, and treatment of other illnesses helps prevent the conditions under which stress ulcers occur. Patients who develop stress ulcers typically do not secrete large quantities of gastric acid; however, acid does appear to be involved in the pathogenesis of the lesions. Thus it is reasonable either to neutralize acid or to inhibit its secretion in patients at high risk.

In case of severe hemorrhagic or erosive gastritis and stress ulcers, a combination of antacids and H2-blockers may stop active bleeding and prevent re bleeding. In selected patients, either endoscopic therapy or selective infusion of vasopressin into the left gastric artery may help control the hemorrhage.

Internationally, the NPUAP, EPUAP and Pan Pacific Pressure Injury Alliance (Australia, New Zealand, Singapore and Hong Kong) published updated evidence-based clinical practice guidelines in 2014. The guideline was developed by an international team of over 100 clinical specialists and updates the 2009 EPUAP and NPUAP clinical guidelines. The guideline includes recommendations on strategies to treat pressure ulcers, including the use of bed rest, pressure redistributing support surfaces, nutritional support, repositioning, wound care (e.g. debridement, wound dressings) and biophysical agents (e.g. electrical stimulation). Reliable scientific evidence to support the use of many of these interventions, though, is lacking. More research is needed to assess how to best support the treatment of pressure ulcers, for example by repositioning.

Necrotic tissue should be removed in most pressure ulcers. The heel is an exception in many cases when the limb has an inadequate blood supply. Necrotic tissue is an ideal area for bacterial growth, which has the ability to greatly compromise wound healing. There are five ways to remove necrotic tissue.

1. Autolytic debridement is the use of moist dressings to promote autolysis with the body's own enzymes and white blood cells. It is a slow process, but mostly painless, and is most effective in individuals with a properly functioning immune system.

2. Biological debridement, or maggot debridement therapy, is the use of medical maggots to feed on necrotic tissue and therefore clean the wound of excess bacteria. Although this fell out of favor for many years, in January 2004, the FDA approved maggots as a live medical device.

3. Chemical debridement, or enzymatic debridement, is the use of prescribed enzymes that promote the removal of necrotic tissue.

4. Mechanical debridement, is the use of debriding dressings, whirlpool or ultrasound for slough in a stable wound

5. Surgical debridement, or sharp debridement, is the fastest method, as it allows a surgeon to quickly remove dead tissue.

Pentoxifylline is a useful add on treatment to compression stockings and may also help by itself. It works by reducing platelet aggregation and thrombus formation. Gastrointestinal disturbances were reported as a potential adverse effect.

Sulodexide, which reduces the formation of blood clots and reduces inflammation, may improve the healing of venous ulcers when taken in conjunction with proper local wound care. Further research is necessary to determine potential adverse effects, the effectiveness, and the dosing protocol for sulodexide treatment.

An oral dose of aspirin is being investigated as a potential treatment option for people with venous ulcers. A 2016 Cochrane systematic review concluded that further research is necessary before this treatment option can be confirmed to be safe and effective.

Oral zinc supplements have not been proven to be effective in aiding the healing of venous ulcers, however more research is necessary to confirm these results.

Treatment is cause-related, but also symptomatic if the underlying cause is unknown or not correctable. It is also important to note that most ulcers will heal completely without any intervention. Treatment can range from simply smoothing or removing a local cause of trauma, to addressing underlying factors such as dry mouth or substituting a problem medication. Maintaining good oral hygiene and use of an antiseptic mouthwash or spray (e.g. chlorhexidine) can prevent secondary infection and therefore hasten healing. A topical analgesic (e.g. benzydamine mouthwash) may reduce pain. Topical (gels, creams or inhalers) or systemic steroids may be used to reduce inflammation. An antifungal drug may be used to prevent oral candidiasis developing in those who use prolonged steroids. People with mouth ulcers may prefer to avoid hot or spicy foods, which can increase the pain. Self-inflicted ulceration can be difficult to manage, and psychiatric input may be required in some people.

Non-elastic, ambulatory, below knee (BK) compression counters the impact of reflux on venous pump failure. Compression therapy is used for venous leg ulcers and can decrease blood vessel diameter and pressure, which increases their effectiveness, preventing blood from flowing backwards. Compression is also used to decrease release of inflammatory cytokines, lower the amount of fluid leaking from capillaries and therefore prevent swelling, and prevent clotting by decreasing activation of thrombin and increasing that of plasmin. Compression is applied using elastic bandages or boots specifically designed for the purpose.

Regarding effectiveness, compression dressings improve healing. It is not clear whether non-elastic systems are better than a multilayer elastic system. Patients should wear as much compression as is comfortable. The type of dressing applied beneath the compression does not seem to matter, and hydrocolloid is not better than simple low adherent dressings. Recently there have been clinical studies on a multi-functional botanical-based ointment in combination with compression therapy in the treatment of difficult-to-heal wounds, including venous leg ulcers.

Intermittent pneumatic compression devices may be used, but it is not clear that they are superior to simple compression dressings.

It is not clear if interventions that are aimed to help people adhere to compression therapy are effective. More research is needed in this field.

The vast majority of people with aphthous stomatitis have minor symptoms and do not require any specific therapy. The pain is often tolerable with simple dietary modification during an episode of ulceration such as avoiding spicy and acidic foods and beverages. Many different topical and systemic medications have been proposed (see table), sometimes showing little or no evidence of usefulness when formally investigated. Some of the results of interventions for RAS may in truth represent a placebo effect. No therapy is curative, with treatment aiming to relieve pain, promote healing and reduce the frequency of episodes of ulceration.

The first line therapy for aphthous stomatitis is topical agents rather than systemic medication, with topical corticosteroids being the mainstay treatment. Systemic treatment is usually reserved for severe disease due to the risk of adverse side effects associated with many of these agents. A systematic review found that no single systemic intervention was found to be effective. Good oral hygiene is important to prevent secondary infection of the ulcers.

Occasionally, in females where ulceration is correlated to the menstrual cycle or to birth control pills, progestogen or a change in birth control may be beneficial. Use of nicotine replacement therapy for people who have developed oral ulceration after stopping smoking has also been reported. Starting smoking again does not usually lessen the condition. Trauma can be reduced by avoiding rough or sharp foodstuffs and by brushing teeth with care. If sodium lauryl sulfate is suspected to be the cause, avoidance of products containing this chemical may be useful and prevent recurrence in some individuals. Similarly patch testing may indicate that food allergy is responsible, and the diet modified accordingly. If investigations reveal deficiency states, correction of the deficiency may result in resolution of the ulceration. For example, there is some evidence that vitamin B12 supplementation may prevent recurrence in some individuals.

Skin ulcers may take a very long time to heal. Treatment is typically to avoid the ulcer getting infected, remove any excess discharge, maintain a moist wound environment, control the edema, and ease pain caused by nerve and tissue damage.

Topical antibiotics are normally used to prevent the ulcer getting infected, and the wound or ulcer is usually kept clear of dead tissue through surgical debridement.

Commonly, as a part of the treatment, patients are advised to change their lifestyle if possible and to change their diet. Improving the circulation is important in treating skin ulcers, and patients are consequently usually recommended to exercise, stop smoking, and lose weight.

In recent years, advances have been made in accelerating healing of chronic wounds and ulcers. Chronic wounds produce fewer growth hormones than necessary for healing tissue, and healing may be accelerated by replacing or stimulating growth factors while controlling the formation of other substances that work against them.

Leg ulcers can be prevented by using compression stockings to prevent blood pooling and back flow. It is likely that a person who has had a skin ulcer will have it again; use of compression stockings every day for at least 5 years after the skin ulcer has healed may help to prevent recurrence.

H2 antagonists or proton-pump inhibitors decrease the amount of acid in the stomach, helping with healing of ulcers.

When "H. pylori" infection is present, the most effective treatments are combinations of 2 antibiotics (e.g. clarithromycin, amoxicillin, tetracycline, metronidazole) and a proton-pump inhibitor (PPI), sometimes together with a bismuth compound. In complicated, treatment-resistant cases, 3 antibiotics (e.g. amoxicillin + clarithromycin + metronidazole) may be used together with a PPI and sometimes with bismuth compound. An effective first-line therapy for uncomplicated cases would be amoxicillin + metronidazole + pantoprazole (a PPI).

These ulcers are difficult to heal by basic wound care and require advanced therapy, such as hyperbaric oxygen therapy or bioengineered skin substitutes. If not taken care of in time, there are very high chances that these may become infected and eventually may have to be amputated. Individuals with history of previous ulcerations are 36 times more likely to develop another ulcer.

The ulcers can be removed through fulguration (burned off with the use of electricity or a laser) or resection (cutting around the ulcer, removing both the ulcer and the surrounding inflamed tissue). Some ulcers may recur in the same location.

Many patients choose to live with the ulcers and treat the symptoms associated with them through bladder instillations and/or pain medication/therapy.

Patients with interstitial cystitis may find relief by modifying their diet to remove foods and beverages that trigger symptoms. Caffeinated beverages, particularly coffee (regular and decaf), tea, green tea, soda, artificial sugars and fruit juices. Cranberry juice may also trigger intense pain and discomfort. However, studies about the impact of specific foods and drinks on Hunner's ulcer symptoms are limited.

The length of antibiotic courses depend on the severity of the infection and whether bone infection is involved but can range from 1 week to 6 weeks or more. Current recommendations are that antibiotics are only used when there is evidence of infection and continued until there is evidence that the infection has cleared, instead of evidence of ulcer healing. Choice of antibiotic depends on common local bacterial strains known to infect ulcers. Microbiological swabs are believed to be of limited value in identifying causative strain. Microbiological investigation is of value in cases of osteomyelitis. Most ulcer infections involve multiple microorganisms.

There are many types of dressings used to treat diabetic foot ulcers such as absorptive fillers, hydrogel dressings, and hydrocolloids. There is no good evidence that one type of dressing is better than another for diabetic foot ulcers. In selecting dressings for chronic non healing wounds it is recommended that the cost of the product be taken into account.

Hydrogel dressings may have shown a slight advantage over standard dressings, but the quality of the research is of concern. Dressings and creams containing silver have not been properly studied nor have alginate dressings. Biologically active bandages that combine hydrogel and hydrocolloid traits are available, however more research needs to be conducted as to the efficacy of this option over others.

Proper diagnosis is essential for optimal treatment. Bacterial corneal ulcer require intensive fortified antibiotic therapy to treat the infection. Fungal corneal ulcers require intensive application of topical anti-fungal agents. Viral corneal ulceration caused by herpes virus may respond to antivirals like topical acyclovir ointment instilled at least five times a day. Alongside, supportive therapy like pain medications are given, including topical cycloplegics like atropine or homatropine to dilate the pupil and thereby stop spasms of the ciliary muscle. Superficial ulcers may heal in less than a week. Deep ulcers and descemetoceles may require conjunctival grafts or conjunctival flaps, soft contact lenses, or corneal transplant. Proper nutrition, including protein intake and Vitamin C are usually advised. In cases of Keratomalacia, where the corneal ulceration is due to a deficiency of Vitamin A, supplementation of the Vitamin A by oral or intramuscular route is given. Drugs that are usually contraindicated in corneal ulcer are topical corticosteroids and anesthetics - these should not be used on any type of corneal ulcer because they prevent healing, may lead to superinfection with fungi and other bacteria and will often make the condition much worse.

Underlying cause of neuropathy is first treated. Necrotic portions of the wound are removed and wound is kept moist at associations. Infected ulcers are administered antibiotics.

Skin grafting is one of the options. It has been shown that ultrasound may increase the acceptance of graft at trophic ulcer sites.

The prevalence of arterial insufficiency ulcers among people with Diabetes is high due to decreased blood flow caused by the thinning of arteries and the lack of sensation due to diabetic neuropathy. Prevention is the first step in avoiding the development of an arterial insufficiency ulcer. These steps could include annual podiatry check ups that include, "assessment of skin, checking of pedal pulses (assessing for blood flow) and assessing physical sensation".

The management of arterial insufficiency ulcers depends on the severity of the underlying arterial insufficiency. The affected region can sometimes be revascularized via vascular bypass or angioplasty. If infection is present, appropriate antibiotics are prescribed. When proper blood flow is established, debridement is performed. If the wound is plantar (on walking surface of foot), patient is advised to give rest to foot to avoid enlargement of the ulcer. Proper glycemic control in diabetics is important. Smoking should be avoided to aid wound healing.

Antacids are a common treatment for mild to medium gastritis. When antacids do not provide enough relief, medications such as H blockers and proton-pump inhibitors that help reduce the amount of acid are often prescribed.

Cytoprotective agents are designed to help protect the tissues that line the stomach and small intestine. They include the medications sucralfate and misoprostol. If NSAIDs are being taken regularly, one of these medications to protect the stomach may also be taken. Another cytoprotective agent is bismuth subsalicylate.

Several regimens are used to treat "H. pylori" infection. Most use a combination of two antibiotics and a proton pump inhibitor. Sometimes bismuth is added to the regimen.

It is diagnosed and treated endoscopically; however, endoscopic ultrasound or angiography can be of benefit.

Endoscopic techniques used in the treatment include epinephrine injection followed by bipolar or monopolar electrocoagulation, injection sclerotherapy, heater probe, laser photocoagulation, hemoclipping or banding. Alternatively, in patients with refractory bleeding Interventional Radiology may be consulted for an angiogram with subselective embolization.

Treatment may consist of topical applications of steroid based creams and the use of compression stockings to help force the underlying buildup of fluids back out of the lower leg or intermittent pneumatic compression pumps.

Topical antibiotics are used at hourly intervals to treat infectious corneal ulcers. Cycloplegic eye drops are applied to give rest to the eye. Pain medications are given as needed. Loose epithelium and ulcer base can be scraped off and sent for culture sensitivity studies to find out the pathogenic organism. This helps in choosing appropriate antibiotics. Complete healing takes anywhere from about a few weeks to several months.

Refractory corneal ulcers can take a long time to heal, sometimes months. In case of progressive or non-healing ulcers, surgical intervention by an ophthalmologist with corneal transplantation may be required to save the eye. In all corneal ulcers it is important to rule out predisposing factors like diabetes mellitus and immunodeficiency.

The mortality rate for Dieulafoy's was much higher before the era of endoscopy, where open surgery was the only treatment option.

Adequate footwear is important to prevent trauma. General good health and nutrition also reduce ulcer risk. Adequate and prompt cleansing and treatment of ankle and leg skin breaks is also important. Improving hygiene and nutrition may help to prevent tropical ulcers.
