What are the causes of diarrhea?

Generally, diarrhea may be caused by underdeveloped digestive function, dietary factors, irritable bowel syndrome, bacterial dysentery, acute enteritis, and other reasons. If discomfort occurs, it is recommended to seek timely medical attention and receive treatment under the guidance of a physician. Detailed explanations are as follows:

1. Underdeveloped Digestive Function

This condition is commonly seen in infants and young children. Due to the immature development of the digestive system, there may be insufficient ability to digest and absorb certain components in food, such as lactose and proteins. It is important to adjust the diet in daily life and avoid foods that are difficult to digest.

2. Dietary Factors

Excessive food intake or consumption of indigestible or allergenic foods can increase the burden on the intestines, leading to increased intestinal secretion and accelerated peristalsis, thereby causing diarrhea. One should adjust the diet and avoid irritating foods.

3. Irritable Bowel Syndrome

Irritable bowel syndrome may be related to abnormal gastrointestinal motility, visceral perception abnormalities, and psychological factors. This type of disorder can cause disordered intestinal peristalsis, resulting in symptoms such as diarrhea or constipation. It may be accompanied by abdominal pain and discomfort. Treatment may involve the use of medications such as live bacillus licheniformis granules, lactobacillus tablets, and lactulose oral solution, as directed by a physician.

4. Bacterial Dysentery

Bacterial dysentery is primarily caused by infection with Shigella bacteria. The bacteria invade the intestinal mucosa, causing inflammation and exudation, which leads to the aforementioned symptoms. It may be accompanied by abdominal pain and diarrhea. Treatment should be carried out under the guidance of a physician using medications such as cefalexin granules, levofloxacin hydrochloride capsules, and azithromycin dispersible tablets.

5. Acute Enteritis

Acute enteritis is mostly caused by bacterial, viral, or parasitic infections. These pathogens enter the body through contaminated food or water sources, multiply in the intestines, and produce toxins that trigger intestinal inflammation and diarrhea. It may be accompanied by symptoms such as abdominal pain and nausea. Patients should use medications such as levofloxacin tablets, four-strain bifidobacterium tablets, and compound berberine tablets as directed by a physician.

To prevent diarrhea, it is important to maintain a balanced diet, avoid overeating, and refrain from consuming indigestible or allergenic foods. Additionally, maintaining healthy lifestyle habits and a positive mindset is essential for maintaining intestinal health.
