What causes pain in the left lower abdomen?

The abdomen is one of the important parts of the human body, and there are many reasons for pain here. The most common one is that you have just finished a meal and then do strenuous exercise, which will cause abdominal pain. For example, if you suffer from colitis, the disease will cause pain in the lower left abdomen, and it will also affect digestion and absorption, and cause abdominal distension, pain, nausea and other symptoms. So are there any other reasons for the pain in the lower left abdomen?

Causes of left lower abdominal pain:

1. Autoimmune reaction: Most scholars believe that this disease is an autoimmune disease. Because this disease is often complicated by autoimmune diseases (such as autoimmune hemolytic anemia), adrenal cortex hormones can relieve the condition, and anti-colonic epithelial cell antibodies can be detected in the serum of some patients, so it is believed that the occurrence of this disease may be related to autoimmune reactions. In addition, after some patients are infected with intestinal bacteria, they may have an immune response to colon epithelial cell antigens, damaging the colon mucosa, and the patient's lymphocytes have a cytotoxic effect on fetal colon epithelial cells, suggesting that the occurrence of colitis may also be related to abnormal cellular immunity.

In real life, people tend to get sick easily when they are under great work pressure, have heavy psychological burden, or are emotionally tense. Why is that? Experts believe that this is a manifestation of the autonomic nervous system affecting the immune system. When the autonomic nervous system is dysfunctional, the immune system will also be dysfunctional, leading to various stubborn diseases.

For example: normal activity of the parasympathetic nerves can promote the secretion of saliva, gastric juice, intestinal juice, pancreatic juice and insulin. When the parasympathetic nerve activity weakens and persists, the decrease in intestinal juice leads to an imbalance of intestinal flora, and colitis cannot be cured for a long time. "Neuroimmune agents" have a special effect on regulating the sympathetic and parasympathetic nerves, and using them to treat colitis has achieved unexpected results.

2. Infection: The pathological changes and clinical manifestations of this disease are similar to those of some colon infectious diseases (such as bacillary dysentery), so some people believe that infection is the cause of this disease. Among various factors such as bacteria, fungi and viruses, current research shows that viruses are more likely.

3. Genetics: The incidence of this disease is relatively high in blood-related families. According to statistics from European and American literature, about 15-30% of the direct blood relatives of patients with ulcerative colitis will develop the disease. In addition, studies on twins have shown that monozygosity is more likely to develop the disease than dizygosity, suggesting that the occurrence of this disease may be related to genetic factors.

4. Neuropsychiatric factors: Some people believe that mental factors play a certain role in the onset of the disease. Most patients have certain personality traits and have poor psychological tolerance and adaptability to major events in life. They belong to the category of psychosomatic disease. Psychosomatic disease emphasizes that psychological factors play an important role in the occurrence or course of the disease. Some people list 7 diseases as psychosomatic diseases, namely: asthma, rheumatoid arthritis, ulcerative colitis, primary hypertension, neurodermatitis, hyperthyroidism and duodenal ulcer. There are probably many more conditions that are currently classified as psychosomatic.

The pace of life in today's society is fast, and more and more people are slowly suffering from this disease. Please ask experts to prescribe effective prescriptions for this disease to solve this disease for the majority of patients.
