When there is gas in the intestines, a feeling of discomfort occurs in the rectal area.

In general, discomfort caused by rectal distension may result from non-pathological factors, or it could be due to pathological conditions such as constipation or indigestion. Patients should seek symptomatic treatment under the guidance of a physician. The specific analysis is as follows:

1. Non-pathological factors

This may be caused by poor dietary and lifestyle habits, such as excessive consumption of raw or cold foods, or abdominal exposure to cold, leading to excessive gas accumulation in the intestines and resulting in intestinal bloating. In such cases, it is recommended to pay attention to dietary balance, reduce intake of raw and cold foods, and maintain healthy lifestyle habits.

2. Pathological factors

1) Constipation
In cases of constipation, bowel movement frequency decreases, and stools become reduced in volume and dry. Common symptoms include loss of appetite, abdominal pain and bloating, reduced frequency of defecation, difficulty passing stool, and rectal distension. Under medical guidance, patients may take oral medications such as mosapride citrate tablets or lactulose oral solution.

2) Indigestion
Indigestion is primarily caused by factors such as Helicobacter pylori infection or gastrointestinal motility disorders. Typical symptoms include postprandial fullness and a burning sensation in the upper abdomen. Rectal distension may also occur. Under medical supervision, patients may take oral medications such as domperidone tablets or itopride hydrochloride tablets.

Besides the three common causes mentioned above, rectal distension may also be caused by organic diseases such as chronic gastroenteritis, hepatobiliary disorders, or pancreatitis. It is strongly recommended to promptly visit a hospital for proper diagnosis and treatment to identify the underlying cause and prevent disease progression.
