  1. The cause lactose intolerance

The cause of lactose intolerance is that the body does not produce enough lactase enzyme to absorb lactose. For most people, the small intestine begins to produce less lactase after two years of age or after weaning. However, later patients can still eat dairy products without symptoms.

Digestive diseases such as Crohn’s disease and celiac disease which is a gastrointestinal disease that destroys the small intestine and obstructs the absorption of nutrients from the food, inflammation or trauma to the small intestine can reduce available lactase levels.

Lactose intolerance is a fairly common disease. Anyone can get it, but most are African Americans, Asians and Mexican Americans. Most people with lactose intolerance can still control the condition without having to give up all dairy foods.

Factors that make you or your child lactose intolerant including

Age. Lactose intolerance is more common in older adults and is less common in infants and young children

Race. This disease is most common in blacks, Asians, Spanish, and Americans.

Preterm birth. Babies with preterm delivery have the potential to reduce lactase levels as this enzyme increases in a late fetus in the third trimester.

Diseases that affect the small intestine. Problems with the bowel can cause lactose intolerance including bacterial growth, Crohn’s disease or celiac disease.

Some cures for cancer. If you receive radiation therapy to treat abdominal cancer or have had chemotherapy-related complications, your risk for lactose intolerance is higher.

  1. How to treatment

To diagnose the disease, your doctor will ask you for a medical history and physical examination. Your doctor will also perform tests to measure lactose uptake in the digestive tract such as lactose intolerance, breathalyzed breath tests, and fecal acid testing for children. In case of unclear basis, the doctor will take a small tissue sample from the small intestine to study.

Infants and young children should not eat lactose-free foods. Adults and older children usually do not need to avoid lactose completely, but you should know the amount of lactose they can absorb based on the symptoms that appear. Calcium is essential for children, adolescents, pregnant women, lactating women or premenopausal women. Avoiding dairy products can make you lose calcium and vitamin D so you need to supplement them with calcium supplements or eat foods rich in calcium such as shrimp, broccoli, green leafy vegetables. Another way is to take lactase enzyme to improve lactose tolerance. Symptoms usually resolve after 3 weeks of discontinuation of dairy products.
