Milk Side Effects: Milk has long been considered a complete food. Being rich in calcium, protein, Vitamin D and many essential nutrients, it is said to be beneficial for everyone from children to the elderly. However, not every person’s body is the same. For some people, milk is an excellent source of nutrition, while for others it can cause digestive problems, allergies or other health problems. Therefore, just thinking that milk is always beneficial, it is not considered right to consume it.

Experts believe that if a person already has any specific health condition, then he should definitely consult a doctor or dietician before drinking milk. Ignoring body signals can increase problems. Let us know about 5 such health conditions in which milk should be consumed wisely.

lactose intolerance
If problems like flatulence, gas, diarrhea, stomach pain or cramps start occurring after drinking milk, then it can be a sign of lactose intolerance. In this condition, the enzyme that digests lactose (lactase) is not produced in sufficient quantity in the body. Such people should adopt lactose-free milk or other alternatives as per doctor’s advice instead of normal milk.

allergy to milk
Some people are allergic to the proteins present in milk. In such a situation, after drinking milk, skin rashes, itching, swelling, difficulty in breathing or severe allergic reaction may occur. This problem is seen more in children, but can also occur in adults. Such people should stay away from milk and its products.

irritable bowel syndrome
Milk can sometimes worsen stomach symptoms in people suffering from IBS. Complaints like stomach ache, gas, cramps and diarrhea may increase after drinking milk. However, its effect may be different in every patient. If drinking milk causes frequent problems, it is better to change the diet after consulting a doctor.

acne problem
Some research has indicated that excessive amounts of milk, especially skimmed milk, may increase the problem of acne in some people. However, it does not affect all people. If pimples are increasing again and again after consuming milk, it would be advisable to consult a dermatologist or nutritionist.

certain kidney diseases
In some serious kidney problems, doctors advise to control the amount of phosphorus, potassium and protein. In such cases, drinking excessive milk can be harmful. Kidney patients should always decide their diet as per the advice of a doctor or dietitian.
