These bacteria live in the intestine of the cattle, chicken and duck. They do not cause any disease in these animals. Humans can develop food poisoning if they drink milk; eat meat or egg contaminated with these bacteria. The unpasteurized milk and improperly cooked meat can increase the chance of infection.

Causes:

If a person eat more than his body requirement, the surplus food is stored as fat. So, he/she becomes overweight or obese. These fats are stored in the adipose tissues in abdomen, around the kidney and under the skin.

Formation of Adipose Tissues:

Certain cells accumulate drops of fats in their cytoplasm. These crops keep on increasing in size and number. These fat drops join together to form one large globule of fat in the middle of the cells. It pushes the nucleus to one side and cytoplasm forms a thin layer. Groups of fat cells form adipose tissue.

Some people eat too much but do not become fat. Some persons become fat when they take a small amount of excess food then their requirement. So, the obesity is a hereditary character. It depends on balance of certain hormones.

6.     Piles or Hemorrhoids

Piles are masses of dilated, tortuous veins in the anorectal mucosa (mucous membrane of rectum and anus). Sometimes, these masses of veins start bleeding during bowl (rectum) movements. The situation becomes complicated when the patients also suffer from constipation.

The urge to defecate is depressed and it becomes difficult to expel the feces. There can be physical distension (swelling) of rectum. This distension of rectum may cause other symptoms of ill health.

Treatment:

There should be improvement in the hygienic conditions. Food softeners like roughage (fibrous food) and laxative should be used. The patient should not have to sit on hard seats. Sometimes, piles have to be removed surgically.

7.     Ulcer

The inner wall of the digestive tract is covered with mucous. Mucous protects the inner membrane from the action of enzymes. If the mucous layer is broken, the digestive enzymes start eating the wall of stomach and duodenum. This results in a sore called ulcer.

In some cases, the ulcer is so severe that a hole develops in the wall of the digestive tract. So, the content of the digestive tract come out into the abdominal cavity. It causes severe infection. If immediate medical care is not given, it may prove to be a fatal. Excess gastric acid secretion is an important factor of the peptic ulcer.

Preventions:

The patients of ulcer should avoid from smoking, spicy food, alcoholic beverages, coffee, tea and stress.
