### condition:

Ulcer
* Most ulcer causes pain.
* Most ulcers are caused by an infection from bacteria
  - round or oval, but some are linear, triangular, or irregular in shape
  - treatable with medications that inhibit the acid producing cells of the stomach
  - develop in the stomach or in the upper part of the small intestine
  - occur in the first part of the small intestine just past the stomach
* Some ulcer destroys ear cartilages.
* Some ulcer is caused by aspirin
  - ethanols
  - fungal infection
  * An 'ulcer' kind of open wound. Ulcers can be on surfaces of the body. They can be on skin. They can be mucous membranes like the surface of the stomach or inside the mouth.
  * can be from infection with germs. Ulcers can be from pressure on a part of the skin. Ulcers can be from substances that will burn skin or mucous membranes. When acid makes some stomach ulcers this is from burning by the acid. Ulcers can be from cancer. Ulcers can be from diseases of blood vessels.

* affect both men and women.
* also occur as a result of over secretion of acid
  - pose their own particular problems and require special dressings under the bandages
* appear and reduce the amount of nutrients that the intestine can absorb.
* are a bacterial disease and can be cured
  - common plague of koi and goldfish
  - result of damage done to the upper lining in the stomach by acid
  - acute and chronic
  - also more likely to cause death in smokers
* are common among the poor classes
  - in Britain and men are more prone to suffer than women
  - contagious
  - dark, even black, and discharge black blood
  - defects in the gastrointestinal mucosa that penetrate the muscularis mucosa
  - focal loss of the epidermis and at least part of the dermis
  - generally a result of poor husbandry
  - internal wounds in the inner lining of the intestine
  - linked to breakdown of the a. pyloric sphincter
  - more common and less likely to heal in smokers than in non-smokers
* are more common in adults than in children
  - smokers and they take longer to heal
  - rare in children and are more likely to occur as people get older
  - red sores that are filled with pus
  - seen on the skin
  - slow to heal but almost always eventually close
  - small craters or sores that form in the lining of the stomach or duodenum
  - sores that form in the digestive tract
  - tears or breaks in the lining of the intestines that can cause sores
* are the leading cause of lower extremity amputations
  - lower-extremity amputations
* are usually fairly small and painful
  - multiple and purulent though second site of infection is common
  - painless
* become more irregular, with variations in size, shape and appearance.
* bleed and form great quantities of thick, yellow, offensive, green pus

  - when there is insufficient cirulation
* especially occur during the spring and fall, and tend to run in families.
* eventually scab over and heal.
* form all over the nasal mucous membrane
  - as a result of the perivascular and vascular necrosis
  - on the inner intestinal lining and eventually spread through the intestinal wall
* form when harmful disease-causing germs invade a sore or wound site
  - the inflamed areas die and slough off, forming a sore in the lining of the bowel
* generally heal completely.
* is injuries
  - located in stomachs
* occur elsewhere, as in the gut and on the skin
  - if stomach acid erodes a hole in the lining of the digestive tract
* occurs only in the presence of acid and pepsin.
* often accompany a hiatal hernia
  - develop in areas where there has been chronic pressure for many years
* often form on a rocker-bottom foot
  - producing mucus, pus and causing bleeding
* predispose the dogs to vomiting.
* represent a severe form of vascular disease and require immediate attention.
* require medical care, especially if there is bleeding.
* result when there's a breakdown in the stomach's protective lining of mucous.
* show up as craters or pits in the lining of the stomach and duodenum.
* sometimes can lead to other problems
