How Lactose Intolerance Triggers Constipation and Ways to Find Relief

Lactose intolerance is a common digestive issue caused by the body’s inability to break down lactose, a sugar found in milk. It can lead to symptoms such as constipation, which affects bowel movements and their frequency. Constipation is defined as having hard stools or fewer than three bowel movements a week. In about 30% of cases, lactose intolerance contributes to this condition. Symptoms usually appear within one to two hours after consuming lactose.

Reducing or cutting out lactose from the diet can ease constipation and other related symptoms. Many people with lactose intolerance can still tolerate up to 12 grams of lactose without discomfort. Lactase enzyme supplements, like Lactaid, may also prevent or relieve symptoms.

For general constipation relief, increasing fibre intake, drinking more water, and regular exercise can help. However, severe cases with rectal bleeding, blood in stool, or intense abdominal pain need urgent medical care. If lactose intolerance symptoms persist beyond a week, a doctor should be consulted. Lactose intolerance can cause constipation, but dietary changes and supplements often provide relief. Most people manage symptoms by adjusting their lactose intake. Medical advice is necessary for severe or prolonged cases.
