Lactose Intolerance Symptoms, Causes, Effects And Treatment: Learn All About The Condition


Lactose Intolerance Symptoms Causes Effects

There is a difference between milk lovers and those who can’t digest milk. The former are lactose- tolerant whereas the latter are lactose-intolerant. Which category do you fall in? Do I see only kids saying NO when it comes to drinking milk or even adults? In both the situations, it is time to know lactose intolerance symptoms, causes, effects.

Lactose Intolerance Symptoms Causes Effects

Causes Of Lactose Intolerance:

What causes lactose intolerance? Any clue? This condition affects people who are unable to digest the sugar (or lactose) in milk.

And when does that happen? When the small intestine in the human body fails to produce enough of lactase enzyme to digest milk sugar i.e. lactose.

If you are deficient in lactase, then the lactose in your food does not get processed and absorbed and moves into the colon instead. Once in the colon, the bacteria make use of the undigested lactose, thereby triggering the lactose intolerance symptoms. Although this condition is harmless, just the symptoms and after-effects get to be pesky and troublesome.

There are two types of lactose intolerance –

  • The Primary stage where lactase production reduces drastically in your body. This makes it difficult for the digestion of milk products to happen as one enters the adulthood phase.
  • The Secondary stage happens when the lactase production is adversely affected due to the following factors – illness, injury or surgery of the small intestine.

Causes Of Lactose Intolerance

Symptoms Of Lactose Intolerance:

The lactose intolerance symptoms are simple to identify. If you are eating or drinking foods that contain lactose, then the signs of intolerance will begin to show up 30 minutes to 2 hours after consumption.

The lactose intolerance effects In a nutshell are:

  • Diarrhea
  • Nausea
  • Abdominal Cramps
  • Bloating
  • Gas

Symptoms Of Lactose Intolerance

What about Constipation? No, it is not a sign of lactose intolerance.

  • Bread
  • Baked goods
  • Processed breakfast cereals
  • Instant foods, soups, and breakfast drinks
  • Margarine
  • Lunch meats (except those that are kosher)
  • Salad dressings
  • Candies
  • Chips and other processed snacks
  • Mixes for pancakes, biscuits, and cookies
  • Soft cheese
  • Milk
  • Nondairy whipped toppings
  • Nondairy liquid and powdered coffee creamers

It is vital that you as a smart shopper read food labels with care. Look beyond the words like “milk” and “lactose” in the contents. Watch out for words such as whey, curds, milk by-products, dry milk solids, and nonfat dry milk powder. If the food label has any of these words, then the food item contains lactose and should be therefore skipped by those who are lactose-intolerant.

Lactose Rich Foods To Avoid

Is Lactose There In Drugs or Medications?

Apart from food sources, lactose can be present in medicines. In fact, lactose is used as a base for making several prescriptions and OTC medications. Some tablets used for treating acidity and flatulence and many types of birth control pills contain lactose. It may be noted that these products do not affect one and all, but only people down with severe lactose intolerance.

Treatment For Lactose Intolerance: The Do’s And Dont’s

Dietary changes are the first and foremost thing that needs to be practiced to tackle lactose intolerance. This means reducing the amount of lactose in the diet. Most people who are averse to lactose in diet can tolerate small to moderate amounts of lactose. To get a good amount of relief from the lactose-intolerance symptoms, a certain amount of “elimination” (skipping in modern-day parlance) needs to be done of the milk products. It means eliminate only milk, cottage cheese, and ice cream.


Surprisingly, yogurt has lactose in large amounts yet it is well-tolerated by lactose intolerant people. According to research, yogurt has been shown to empty more slowly from the stomach than an equivalent amount of milk.

In addition to yogurt, another milk substitute available which can be considered is Soy and Rice milk.

Those of you who are intolerant to even small amounts of lactose should strictly avoid any purchased product containing the milk sugar.

Bear in mind that when you substitute whole milk or yogurt for non-fat milk, it doesn’t reduce the lactose intolerance symptoms. You have to be very strict with the way and form that you consume lactose.

Treatment for Lactose Intolerance

What About Calcium And Vitamin D Supplements:

We know the best sources of calcium in foods? Undoubtedly it is milk and milk products. No wonder, calcium deficiency can be one of the major side effects of lactose intolerance. This can increase the risk of bone fractures and osteoporosis. As a preventive measure, the body needs to be beefed up with calcium and Vitamin D supplements.

If you think you suffer from lactose intolerance please consult your physician or nutritionist to change your diet accordingly.
