Stomach pain, faint sweat during defecation, and even fainting are mostly considered to be caused by constipation, chronic appendicitis attack, food poisoning and other factors, which should be checked immediately at the hospital to identify the causes and then treated: 1. Constipation: mostly related to poor dietary habits, such as long-term consumption of greasy, spicy and stimulating food, insufficient intake of dietary fiber, which can easily lead to gastrointestinal spasm, slow peristalsis of the gastrointestinal tract, and patients with constipation. If excessive force is exerted during defecation, it can cause insufficient blood supply to the brain and fainting or false sweating. When the symptoms are mild, conservative treatment can be taken by paying attention to more rest, eating as much coarse fiber food and fresh vegetables and fruits as possible, and massaging the abdomen appropriately to promote food digestion. For more serious symptoms, some drugs to promote gastrointestinal peristalsis need to be applied under the guidance of doctors, and if necessary, drugs such as mannitol and polyethylene glycol can be applied to relieve constipation. 2. Food poisoning: Patients who eat food contaminated by bacteria or other toxins can stimulate the gastrointestinal tract to cause pain, and may also be accompanied by symptoms such as dizziness, headache, nausea and vomiting, while neurological food poisoning can lead to increased secretion of sweat glands, resulting in symptoms of false sweating. Suspected food, vomit and feces should be taken for germ culture to clarify the type of pathogenic bacteria, and combined with drug sensitivity test, choose suitable antibiotics for antibacterial treatment, or apply sodium bicarbonate, potassium permanganate solution for gastric lavage to reduce gastrointestinal tract damage; 3. Appendicitis: Bacteria invade into the appendix cavity leading to infection, which may manifest as abdominal pain, accompanied by nausea, vomiting, weakness, chills and other manifestations, which may lead to increased false sweating It may even cause fainting due to unbearable pain. CT and ultrasound examinations can be performed to clarify the diagnosis, and surgical removal is the main treatment.
