Why does lying flat make my stomach feel uncomfortable, and what should I do about it?

The abdomen refers to the abdominal area. Discomfort in the abdomen when lying flat may be caused by physiological reasons, or it could result from pathological conditions such as indigestion or intestinal obstruction. Treatment depends on the specific cause. Details are as follows:

I. Physiological Causes

When lying flat during sleep, abdominal discomfort may occur if the abdomen becomes chilled. This symptom can be relieved by applying heat to the abdominal area.

II. Pathological Causes

1. Indigestion

Overeating or eating excessively can lead to indigestion, weakening gastrointestinal motility and causing discomfort such as bloating and abdominal pain when lying down. Medications such as Jianwei Xiaoshi tablets, domperidone tablets, or compound digestive enzyme capsules may be taken according to medical advice.

2. Intestinal Obstruction

When there is an obstruction in the gastrointestinal tract, gas cannot be expelled normally, leading to abdominal bloating. Symptoms often worsen when lying flat, causing discomfort. Under a doctor's guidance, medications such as domperidone tablets, mosapride citrate tablets, or simethicone tablets may be used to alleviate symptoms.

In addition, conditions such as gastroenteritis, peptic ulcer, or reflux esophagitis may also be responsible. It is recommended that patients seek timely medical evaluation at a hospital for proper diagnosis and treatment based on individual circumstances.
