Why does a senior get diarrhea after drinking milk?

Diarrhea usually refers to loose or watery stools. Diarrhea in elderly individuals after drinking milk may be related to physiological factors, or could result from pathological causes such as milk allergy or lactose intolerance. It is important to identify and treat the underlying cause accordingly. The specific analysis is as follows:

1. Physiological Factors

As people age, their body's resistance declines. Drinking cold milk can irritate the gastrointestinal tract, leading to symptoms such as abdominal pain and diarrhea. It is recommended to keep the abdomen warm, avoid raw or cold foods, and with proper adjustment, symptoms will gradually improve.

2. Pathological Factors

1) Milk Allergy

Milk consists of various components including water, fat, phospholipids, and proteins. If an elderly person is allergic to any of these components, drinking milk may trigger an allergic reaction, resulting in abnormal bowel movements and abdominal pain. It is advised to promptly visit a hospital for allergen testing and receive desensitization treatment as needed.

2) Lactose Intolerance

If an elderly person has not regularly consumed milk for a long time, the body's lactase enzyme levels may gradually decrease. When lactase is deficient or absent, lactose cannot be properly broken down into galactose. As a result, the intestines are unable to absorb lactose after drinking milk, leading to diarrhea and discomfort. First, strictly control daily diet by avoiding high-lactose foods. If necessary, take medications such as lactasin tablets, Bifidobacterium triple viable powder, or lactase capsules as directed by a physician.

In addition, indigestion and other factors may also contribute. It is recommended that elderly individuals drink warm milk, maintain a balanced diet, and reduce intake of raw, cold, or irritating foods.
