Digestive System Dieseases
What is Digestive Systme dieseases?
Digestive System refer to diseases involving the gastrointestinal tract, namely the
esophagus, small intestine, large intestine and rectum, and the accessory organs of digestion, the
liver, gallbladder, Stomach and pancreas.
Types of Digestive system dieseases:
A) Esophagus-
The musculsr tube that carries food and liquid from the mouth to the stomach changes to tissue
that resembles the lining of the intestine. The most common problem with the esophagus is
GERD.
Some of the esophagus dieseases are:
- Esophageal motility disorder
- GERD(Gastroesophageal reflux diesease)
B) Stomach-
The stomach is a muscular organ located on the left side of the upper abdomen. The stomach
receives food from the esophagus. As food reaches the end of the esophagus, it enters the
stomach through a muscular valve called the lower esophageal sphincter.
Some of the Stomach dieseases are:
- Ulcer disease : Perforation and Bleeding
- Gastric outlet obstruction
C) Small intestines-
Small intestine, a long, narrow, folded or coiled tube extending from the stomach to the large
intestine; it is the region where most digestion and absorption of food takes place. It is
about 6.7 to 7.6 metres (22 to 25 feet) long, highly convoluted, and contained in the central
and lower abdominal cavity.
Some of the Small intestine dieseases are:
- Small bowel obstruction
- Small bowel perforation
- Tuberculosis of abdomen
- Superior mesentric artery syndrome
D) Colon-
The colon is also called the large intestine. The ileum (last part of the small intestine)
connects to the cecum (first part of the colon) in the lower right abdomen. Your large
intestine is broken down into six sections including the cecum, ascending colon, transverse
colon, descending colon, sigmoid colon, and the rectum. The colon begins at the end of the
small intestine, where it is called the cecum, and ends at the rectum. Cancers of the large
intestine are casually referred to as colon,rectal or colorectal cancer.
Some of the Colon dieseases are:
- Diverticulitis of colon
E) Spleen-
The spleen is an organ found in virtually all vertebrates. Similar in structure to a large
lymph node, it acts primarily as a blood filter.
Treatments for Spleen dieseases are:
- laparoscopic splenectomy
F) Pancreas-
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In
humans, it is located in the abdomen behind the stomach.As an endocrine gland, it functions
mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin,
and pancreatic polypeptide.
Some of the Pancreas dieseases are:
G) Hepatobiliary disease-
Hepatobiliary disease includes a heterogeneous group of diseases of the liver and biliary
system caused by viral, bacterial, and parasitic infections, neoplasia, toxic chemicals,
alcohol consumption, poor nutrition, metabolic disorders, and cardiac failure.
Some of the Hepatobiliary disease are:
H) Vascular complications of GI tract
-
Vascular lesions of the gastrointestinal (GI) tract include arterio-venous malformations as
angiodysplasia and Dieulafoy's lesion, venous ectasias (multiple phlebectasias and
haemorroids), teleangiectasias which can be associated with hereditary hemorrhagic
teleangiectasia (HHT), Turner's syndrome and systemic sclerosis, haemangioma's, angiosarcoma's
and disorders of connective tissue affecting blood vessels as pseudoxanthoma elasticum and
Ehlers-Danlos's disease.
Some of the Vascular complications of GI tract are:
- Pseudoaneurysm bleeding
