Title: Lactose Intolerance


1
Lactose Intolerance
  • Student Created

2
Definition
  • The inability to digest and absorb lactose (the
    sugar in milk) that results in gastrointestinal
    symptoms when milk or products containing milk
    are drunk or eaten.

3
Causes
  • It is caused by reduced or absent activity of
    lactase that prevents the splitting of lactose.
    This is due to three reasons congenital,
    secondary or developmental.
  • Congenital Absence from birth of lactase due to
    a mutation in the gene responsible for creating
    lactose.
  • Secondary Due to diseases that destroy the
    lining of the small intestine along with the
    lactase.
  • Developmental A decrease in the amount of
    lactase that occurs after childhood and persists
    into adulthood.

4
Risk Factors
  • Age Lactose intolerance usually starts after age
    5 the condition is uncommon in babies and young
    children.
  • Ethnicity Lactose intolerance is more common in
    certain ethnic and racial populations. Lactose
    intolerance is more common in black, Asian,
    Hispanic and American Indian populations.
  • Premature birth Infants born prematurely (28 to
    32 weeks of gestation) may have reduced levels of
    lactase, because this enzyme increases in the
    fetus late in the third trimester.

5
Symptoms
  • Abdominal bloating
  • Abdominal cramps
  • Gas
  • Malnutrition
  • Nausea
  • Slow growth
  • Weight loss
  • Symptoms often occur after you eat or drink milk
    products, and are often relieved by not eating or
    drinking milk products. Large doses of milk
    products may cause worse symptoms.

6
Elimination Diet
  • Most common way to test lactose intolerance.
    (eliminating obvious milk and milk products)
  • Some problems with this are
  • 1. Milk products are so common in prepared foods
    that it is likely that the diet is not as
    rigorous as it should be.
  • 2. Some people do too short a trial.
  • 3. There is a possibility of a placebo effect
    where people think they feel better when they
    actually arent.

7
Treatment
  • Removing milk from the diet usually improves
    symptoms however, not having milk can lead to a
    shortage of calcium, vitamin D, riboflavin, and
    protein. Add other sources of calcium to the diet
    if you remove milk products.
  • You can add lactase enzymes to regular milk or
    take them in capsule or chewable tablet form.
  • You may need to find new ways to get calcium into
    your diet (you need 1,200 - 1,500 mg of calcium
    each day)
  • Take calcium supplements
  • Eat foods that have more calcium (leafy greens,
    oysters, sardines, canned salmon, shrimp, and
    broccoli)
  • Drink orange juice that contains added calcium

8
Treatment cont.
  • These milk products may be easier to digest
  • Buttermilk and cheeses (they have less lactose
    than milk)
  • Fermented milk products, such as yogurt
  • Goat's milk (but drink it with meals, and make
    sure it is supplemented with essential amino
    acids and vitamins if you give it to children)
  • Ice cream, milkshakes, and aged or hard cheeses
  • Lactose-free milk and milk products
  • Lactase-treated cow's milk for older children and
    adults
  • Soy formulas for infants younger than 2 years
  • Soy or rice milk for toddlers

9
Lactose in non-dairy products
  • Sometimes found in
  • Sausages/hot dogs
  • Sliced meats
  • Gravy stock powder
  • Margarines
  • Sliced bread
  • Breakfast cereals
  • Potato chips
  • Dried fruit
  • Processed foods
  • Medications
  • Protein Supplements

10
Alternatives to Soy Milk
  • Many people have difficulty digesting soy
    products.  Some people can tolerate soy but only
    if it is cooked, others only in small amounts. 
    There are several alternative choices available
    with Rice, Almond or Oat milk, each has a
    different flavor so try the various brands until
    you find one you like.  Be sure to buy the
    enriched varieties as they provide as much
    calcium and vitamins A and D as cows milk and
    remember to read the labels, some brands of rice,
    almond, and oat milks are blended with soy.
