Why Does My Stomach Hurt When I Use Force?

There are many important organs in our abdomen, such as the reproductive system and our intestines. If you feel pain when straining your abdomen, the first consideration is whether the pain is caused by muscle strain due to frequent abdominal strain recently. If external forces are excluded, it is likely to be colitis. If you have colitis, you may also experience symptoms such as diarrhea. In this case, you need to seek medical treatment to recover.

1. Viral colitis: Viral colitis is caused by viruses such as canine distemper virus, canine parvovirus, and canine coronavirus. In viral colitis, rotavirus is the main cause of diarrhea in infants and young children, while Norwalk virus is the main cause of epidemic viral gastroenteritis in adults and older children.

2. Bacterial colitis: Bacterial colitis is caused by bacteria such as Escherichia coli, Salmonella, Yersinia (causing enterocolitis), Bacillus capillaris, Campylobacter jejuni, and Clostridium (canine hemorrhagic gastroenteritis). The most common pathogenic bacteria causing bacterial colitis are Shigella, followed by Campylobacter jejuni and Salmonella.

3. Fungal colitis: Fungal colitis is caused by fungi such as Histoplasma capsulatum, algae, Aspergillus, and Candida albicans. Candida albicans is the most common cause of fungal colitis.

4. Parasitic colitis: Parasitic colitis is caused by parasites such as flagellates, coccidia, Toxoplasma gondii, Ascaris lumbricoides, and hookworms. Amoeba histolytica is a common cause of colitis caused by parasites.

5. Colitis caused by diet: Contaminated or spoiled food, irritating chemicals, certain heavy metal poisoning, and certain allergic reactions can all cause colitis.

6. Colitis caused by antibiotics: Abuse of antibiotics can lead to imbalance of intestinal flora or the emergence of antibiotic-resistant strains, which can cause colitis.

1. Acute colitis: In China, the incidence of acute colitis is higher in summer and autumn, with no gender difference. The general incubation period is 12 to 36 hours. Nausea, vomiting, and diarrhea are the main symptoms of acute colitis.

2. Chronic colitis: The clinical manifestations of chronic colitis include long-term chronic or recurrent abdominal pain, diarrhea, and indigestion. In severe cases, there may be mucus or watery stool. The severity of diarrhea varies, with mild cases having 3 to 4 bowel movements per day or alternating between diarrhea and constipation, and severe cases having bowel movements every 1 to 2 hours, or even incontinence. Some patients may have nocturnal diarrhea and/or postprandial diarrhea. When the rectum is severely affected, there may be a sense of urgency and heaviness. The stool is often pasty and mixed with a large amount of mucus and often contains pus and blood. Some patients may have fresh blood in their stool, which is limited to the rectum and is called hemorrhagic rectitis. The blood or stool may be discharged separately or adhere to the surface of normal or dry stool, which is often mistakenly diagnosed as hemorrhoids bleeding. Patients with rectitis often have bloody mucus stool and may even have fecal incontinence. If the lesion extends above the rectum, the blood often mixes with the stool or appears as bloody diarrhea. Physical examination may reveal mild tenderness in the umbilical or lower abdominal region, hyperactive bowel sounds, and rectal prolapse.
