Food Allergies Symptoms and Food Intolerance

Food allergies symptoms and severity vary by person. Different foods can trigger different symptoms. Food reactions usually appear within one hour after eating or less. Here are some symptoms of allergies that may arise:

  • Respiratory tract: coughing, asthma, shortness of breath
  • Mouth: inflammation of the mouth, tongue and palate
  • Body: swelling of the body (angioneurotic edema)
  • Skin: a reddish skin rash (urticaria) that itches and disappears within a few days.
  • Gastrointestinal tract: diarrhea, vomiting, stomach cramps, hard and bloating
  • Eyes: edema, allergic conjunctivitis
  • Nose: a runny nose (rhinitis), sneezing

System: anaphylactic shock (rare), blood pressure, heart rhythm disturbances, palpitations, headaches, fatigue

Food Allergies Symptoms or Intolerance?

Flatulence, muscle or joint pain and fatigue can also occur after a person eats certain foods, but the cause is not allergies but food intolerance. Food intolerance is the response of the digestive system – not the immune system response – which occurs when food substances interfere with your digestive system or you cannot digest or decompose it properly. Lactose intolerance, which is found in milk and milk products, is the most common food intolerance.

What Is Food Intolerance?

Unlike some allergies, food intolerance is not life-threatening. However, it can be very problematic for those affected.

Food intolerance and sensitivity are very common and seem to continue to increase. In fact, it is estimated that up to 20% of the world’s population may have a food intolerance. Food intolerance and sensitivity can be difficult to diagnose due to various food allergies symptoms.

The term “food hypersensitivity” refers to food allergies and food intolerance.

Food intolerance is not the same as food allergies, although some symptoms may be similar.

Actually, it’s difficult to distinguish between food allergies and food intolerance, so it’s important to talk to your doctor if you suspect you have an intolerance.

If you have a food intolerance, symptoms usually begin within a few hours after eating foods that are not tolerant of you.

However, food allergies symptoms can be delayed for up to 48 hours and last for hours or even days, making the offending food very difficult to show.

What’s more, if you often consume foods that are intolerant, it may be difficult to correlate symptoms in certain foods.

While symptoms of food intolerance vary, they most often involve the digestive system, skin and respiratory system.

Common food allergies symptoms include:

  • Rash
  • Flushing of the skin
  • A runny nose
  • Fatigue
  • A headache
  • Diarrhea
  • Stomach ache
  • Reflux
  • Nausea

Bloated food intolerance is usually diagnosed by an elimination diet specifically designed to narrow down the offending food or through other testing methods.

An elimination diet eliminates food that is most often associated with intolerance over a period of time until symptoms subside. Food is then reintroduced one by one while monitoring symptoms.

Food Allergies Symptoms Diagnosis

Allergic diagnosis is usually done by a combination of reviewing the patient’s medical history, clinical examination and tests to detect ige antibodies. A simpler way to identify food reactions is diet rotation, which consists of consuming only certain foods that are replaced every 3-4 days in two or three cycles. This method can identify food allergens.

Handling

After knowing the foods that cause allergies, you should avoid them. However, sometimes this can be difficult because there are hidden ingredients such as additives, nuts, soybeans, milk proteins, etc. Always check and re-check at the packaging or taste. In this case, you should always buy products from the same brand, which you know does not cause allergies. In most cases, the use of antihistamine drugs can reduce swelling and allergic itching.
