Wheat Intolerance Symptoms in Adults

Food Allergies

The conditions, wheat intolerance, gluten intolerance, and gluten allergy are often used interchangeably. However, they differ from each other. The exact cause of wheat intolerance is unknown. There are no human-induced causes for it.

➡ Symptoms

Wheat intolerance can cause numerous signs and symptoms. Many times, the symptoms are vague and not related to the digestive system at all. Due to this reason, this disorder is not diagnosed easily. Following are some of the possible symptoms. Note that this is not an exhaustive list.

Common Symptoms:

  • Headache
  • Muscle ache
  • Skin rash
  • Redness / swelling on skin
  • Palpitations
  • Eczema
  • Lethargy
  • Weight loss
  • Fatigue
  • Joint pain
  • Inflammation

Digestive Disorders:

  • Constipation
  • Diarrhea
  • Stomach cramps / pain
  • Vomiting
  • Bloating
  • Nausea
  • Flatulence
  • Retention of fluids
  • Irritable Bowel Syndrome (IBS)

Respiratory System Symptoms:

  • Cough
  • Wheezing
  • Difficulty in breathing
  • Tightness in chest
  • Difficulty in swallowing
  • Hay fever

Psychological Symptoms:

  • Anxiety
  • Irritability
  • Mood swings
  • Lethargy
  • Cravings
  • Giddiness

Headache, experienced only on one side of the head, abdominal cramps, asthma-like symptoms are the most common signs of wheat intolerance. Bloating is also a common but less severe symptom.

Sometimes, coming in contact with plants of wheat can also trigger off asthma-like symptoms. In the initial stage, the symptoms appear very mild, but, become severe as the time passes. Due to this, food intolerance is difficult to diagnose in the initial stage.

In children, common symptoms like vomiting, diarrhea and skin rash are observed. On the other hand, in case of adults, the symptoms vary from one person to the other. Not all symptoms are observed in every case. However, if these symptoms are observed after consuming wheat products, there can be a possibility of wheat intolerance.

➡ Treatment

In case you observe the aforementioned symptoms, with no obvious cause or after having meal, you should consult the doctor. A medical practitioner will easily diagnose and treat the condition.

Maintaining a food diary every day can help in diagnosing this condition. The doctor may advise the person to completely avoid eating wheat and other gluten containing foods, and then see whether the symptoms subside or not. If the symptoms subside, it is inferred that the person is intolerant to wheat. Whereas, if the symptoms do not subside, it is concluded that they are signs of some other disease or disorder.

Completely excluding wheat and other gluten containing products is the only effective treatment for this disorder. The doctor will also prescribe medication to treat the symptoms and discomfort.

➡ Prevention

Apart from wheat, there are other products that also contain gluten and should be avoided. They include: wheat, wheat germ, wheat grass, rye, barley, bulgur, couscous, farina, graham flour, matzo, semolina, Spelt, oats, etc.

On the other hand, check the labels of the following foods as they might contain wheat or gluten. They include: bread and bread rolls, cakes, croûton, pretzels, muffins, biscuits, cookies, pasta, pizza, scones, pancakes, processed luncheon meats, barley drinks, beer, etc.

Consume only those foods that are marked ‘gluten-free’. Secondly, you should also make sure to know the ingredients of food when eating out. Although wheat intolerance cannot be cured completely, following these measures can help in preventing the condition to a great extent.

As a concluding note, note that it will be wise to consult a dietitian who will draw out a diet plan for you in order to prevent wheat intolerance symptoms and its complications. Take care!


Hi, I'm Angela and welcome to my blog.

I've been interested in allergies and how to manage them since I was diagnosed myself after years of struggling with different conditions. I thought I had to live with them forever, but over time I learned how to control and manage them.

I have compiled in this blog articles that helped me to go through my allergies and get to the other side of the tunnel.

Thanks for stopping by, and I hope you find something to help you along the way.
