Diseases/Disorders
A localized pocket of pus caused by a bacterial infection in the underlying tissues of the anal canal, which can cause tenderness, swelling, and pain. Certain conditions, such as Crohn’s disease (chronic inflammatory bowel disease), can increase the risk of abscess in and around the anal canal.
A tiny channel or tract that develops in the presence of inflammation and infection, and may be associated with an abscess. The channel usually runs from the rectum to an opening in the skin around the anus, but the opening may develop elsewhere in the body, such as in the vagina or bladder. Certain illnesses such as Crohn’s disease can cause fistulas to develop. An abscess and fistula often occur together.
A low red blood cell count or not enough red cells in the body. Symptoms include fatigue, drowsiness, or even shortness of breath on exertion.
A specific type of hepatitis where the body produces antibodies causing the immune system to attack the liver. Autoimmune hepatitis is not caused by a virus or bacteria, so it is not a contagious disease. Exactly what triggers the immune system against the liver is unknown. The inflammation is usually chronic, and without treatment it can cause serious injury to the liver. Early symptoms are the same as those for most types of hepatitis: fatigue, abdominal discomfort, and aching joints.
Blood that passes from your anus, lower colon or rectum, which appears as blood in stool, on toilet paper, or in the toilet bowl. Rectal bleeding may occur for many reasons, including constipation and hemorrhoids.
Scarring or narrowing of the opening of the esophagus or other areas in the digestive tract causing difficulty swallowing and interference with food/liquids getting into the stomach.
A disease that causes ulcers in the lining of the rectum and colon. It is one of a group of diseases called inflammatory bowel disease. Ulcers form where inflammation has killed the cells that usually line the colon. Ulcerative colitis can happen at any age, but it usually starts between the ages of 15 and 30. It tends to run in families. The most common symptoms are pain in the abdomen and bloody diarrhea. Other symptoms may include anemia, severe tiredness, weight loss, loss of appetite, bleeding from the rectum, sores on the skin and joint pain.
