Causes of diarrhea

Diarrhea is a disease medically known as diarrhoea. It is a common disease that affects a wide range of people, including men, women, young and old. Diarrhea is divided into two types: acute diarrhea and chronic diarrhea. I don’t know if you have had this feeling. When you have diarrhea, your stomach will hurt, which seriously affects your normal life and work. If not treated in time, it will lead to the loss of nutrients and even electrolyte disorders. Knowing the cause of diarrhea can help you treat it accordingly.

There are many types of diarrhea, including bacterial, viral, caused by cold, and some gastrointestinal diseases, etc. When diarrhea occurs, you must find out the cause of the diarrhea in time, treat it in time, and do not delay the disease. If the diarrhea does not get better, you should go to the hospital for a comprehensive examination. The following are some of the causes of diarrhea:

1. Acute diarrhea

(1) Bacterial infection: People may develop enteritis or bacillary dysentery after eating food contaminated by bacteria such as Escherichia coli, Salmonella, Shigella, or drinking beverages contaminated by bacteria, with symptoms such as abdominal pain, diarrhea, vomiting, tenesmus, and fever of varying degrees.

(2) Viral infection: When a person is infected with a variety of viruses through food or other means, it is easy to cause viral diarrhea. For example, after being infected with rotavirus, Norwalk virus, Coxsackie virus, Echo virus and other viruses, symptoms such as abdominal pain, diarrhea, nausea, vomiting, fever and general discomfort may occur.

(3) Food poisoning is an acute toxic disease caused by eating food contaminated by bacteria and their toxins, or eating uncooked lentils, etc. Spoiled food and contaminated water are the main sources of infection, while unclean hands, tableware and infected flies are the main routes of transmission. Patients may experience acute gastrointestinal symptoms such as vomiting, diarrhea, abdominal pain, and fever.

(4) Eating raw and cold food and drinking ice beer frequently may lead to gastrointestinal dysfunction, accelerated intestinal motility and diarrhea.

(5) Indigestion, irregular eating habits, overeating, eating indigestible food, or food retention in the stomach due to insufficient gastric motility, causing symptoms such as abdominal distension, diarrhea, nausea, vomiting, acid reflux, heartburn, and belching (hiccups).

(6) Catching a cold In the hot summer, people like to stay in air-conditioned rooms or sleep with the air conditioner on. The abdomen can easily get cold, which speeds up intestinal peristalsis and causes diarrhea.

2. Chronic diarrhea

Chronic diarrhea lasts for more than 2 months and has more complex causes than acute diarrhea, so diagnosis and treatment are sometimes difficult.

(1) Intestinal infectious diseases: ① Chronic amoebic dysentery; ② Chronic bacterial diseases; ③ Intestinal tuberculosis; ④ Giardiasis, schistosomiasis; ⑤ Intestinal candidiasis.

(2) Non-infectious intestinal inflammation: ① Inflammatory bowel disease (Crohn's disease and ulcerative colitis); ② Radiation enteritis; ③ Ischemic colitis; ④ Diverticulitis; ⑤ Uremic enteritis.

(3) Tumors: ① Colorectal cancer; ② Colon adenoma (polyp); ③ Malignant lymphoma of the small intestine; ④ Amine precursor uptake decarboxylation cell tumor, gastrinoma, carcinoid, intestinal vasoactive intestinal polypeptide tumor, etc.

(4) Small intestinal malabsorption ① Primary small intestinal malabsorption; ② Secondary small intestinal malabsorption.

The above introduces the causes of diarrhea, and introduces the diarrhea caused by various reasons. The symptoms are different, and they must be distinguished correctly. If you cannot tell the difference, you must consult a doctor and do not take medicine blindly to cover up your condition. For patients with chronic diarrhea, more attention should be paid to finding out the cause of frequent diarrhea.
