Patients with indigestion may experience upper abdominal pain, nausea, belching, acid reflux, heartburn, or cause diarrhea, or constipation. If patients experience indigestion, they can massage the abdomen clockwise, focusing on the area around the navel. During the massage, gently rub without applying too much force, and hot compresses can also be used for treatment. If the effect is still poor after the above treatments, consider using medication, such as drugs that regulate intestinal flora, and Bacillus cereus can also be used.
