Hot compress can promote the blood circulation in the stomach, accelerate the metabolism of substances in the body, promote the peristalsis of the gastrointestinal tract, facilitate the digestion and absorption of food and avoid constipation. Especially for some patients who are prone to catch cold in the stomach, frequent hot compress on the abdomen can effectively relieve the pain and discomfort in the stomach, which is conducive to the recovery of the patient's condition. But for some patients with intestinal obstruction, it is forbidden to apply hot compress to the abdomen. Hot compress to the abdomen will accelerate intestinal peristalsis, aggravate intestinal obstruction, and even cause strangulated intestinal obstruction, which requires emergency surgery to remove necrotic intestine.
