What causes bloating and a bulge on the right side of the lower abdomen, and what should be done about it?

Swelling and bloating on the right side of the lower abdomen may be caused by physiological factors, or by pathological conditions such as indigestion or appendicitis. Treatment can be achieved through general management or medication. Specific details are as follows:

I. Physiological Factors

If a patient frequently consumes hard-to-digest foods or the abdomen is exposed to cold air, gastrointestinal motility may slow down, leading to bloating and swelling. It is recommended to adjust the diet, focusing on light and easily digestible foods.

II. Pathological Factors

1. Indigestion

Excessive alcohol consumption or overeating may increase the burden on the gastrointestinal tract and lead to indigestion due to slowed gastrointestinal motility. Under bacterial decomposition and fermentation in the intestines, food produces excessive gas, causing abdominal distension and pain. Patients may take medications such as lactasin granules or lactasin tablets under medical guidance.

2. Appendicitis

This is usually caused by obstruction of the appendix cavity, or bacterial or viral infections. Due to inflammatory irritation, symptoms include abdominal pain and bloating. Patients may take medications such as cefixime dispersible tablets or metronidazole tablets under medical supervision.

In addition to the above causes, conditions such as intestinal obstruction, colon tumors, or bile duct tumors may also be responsible. Patients should ensure proper warmth and avoid exposing the abdomen to cold.
