Symptoms of Lactose Intolerance

Lactose intolerance is caused by a lack of the enzyme lactase, which aids in the digestion of sugar (lactose) found in milk. Milk allergy, on the other hand, is a reaction to the proteins contained in milk that causes an allergic reaction. The two illnesses have different symptoms.

Lactose intolerance causes symptoms that are restricted to the gastrointestinal tract while patients with a milk allergy, on the other hand, may experience respiratory and gastrointestinal problems.

Milk allergy generally appears quickly or within a few minutes of exposure, but symptoms might take up to 20 hours to manifest. 

Milk allergy symptoms are:

  • Diarrhoea \ Hives
  • Eyes that are itchy and watery (often red)
  • Lips, tongue, eyes, or facial swelling
  • Chest stiffness
  • Vomiting
  • Consciousness loss or dizziness

Lactose intolerance symptoms can appear minutes or hours after eating lactose-containing foods.

  • Bloating \ Diarrhoea
  • A lot of gas
  • Stomach cramps
