Generally, drinking an appropriate amount of milk every day may not have any negative effects. However, excessive consumption may lead to nutritional excess, weight gain, indigestion, nutritional imbalance, and other negative consequences. Therefore, it is important to control the amount consumed. Here are some specific reasons:

1. Nutritional Excess

Milk is a highly nutritious food that contains rich amounts of protein, vitamins, calcium, and other essential nutrients. Drinking an appropriate amount can provide the body with necessary nutrients. However, excessive consumption may lead to an overabundance of protein in the body, resulting in nutritional excess.

2. Weight Gain

Milk contains a significant amount of fat. Excessive drinking may lead to the accumulation of fat in the body, resulting in weight gain and potential health issues.

3. Indigestion

Milk is high in calcium and protein. Excessive consumption may increase the burden on the gastrointestinal tract, leading to symptoms such as bloating, abdominal pain, and other digestive issues.

4. Nutritional Imbalance

Excessive drinking of milk may interfere with the body's absorption of nutrients from milk. If this occurs for a prolonged period, it may affect the nutritional status of the body, leading to nutritional imbalance.

Other Considerations

Milk also contains a certain amount of lactose. Long-term excessive consumption may increase the risk of developing diabetes. If you experience any discomfort after drinking milk, it is recommended to seek medical attention at a reputable hospital.
