Hi,
Welcome to health care magic,
Diverticuloum is a abnormal outward projection of mucosa of
colon.When it is get infected,it is known as
diverticulitis.Your boy friend must be suffering with this infection
He will have to take antibiotics ( quinolones or cephalosporins) with antiprotozoals like
metronidazole,antiemetics,antispasmodics, probiotics and other supportive treatment and your family physician may prescribe it.
Also, you have to be careful regarding dietary restrictions which should be low fat and high protein.
He can have a below mentioned diet.
1)Eat healthy carbohydrates like fruits, vegetables and whole grains.
2) Drink at least 2 glasses of milk, replace tea with milk.
3) Have eggs for breakfast.
4) have all kinds of fruit juices and drink plenty of water throughout day. Custard is good for putting on weight
But the main cure is the only surgical removal of diverticulam because of repeated gut infection or they could be also chances of complications like peritonie,bowel obstruction etc.
