25 Signs That Indicate One Might Have A Food Intolerance

15. Respiratory problems

If you experience a runny nose (rhinitis) or sinusitis on a recurring basis due to food intolerance, it might be accompanied by respiratory problems such as shortness of breath. Although rhinitis can be treated with various medications, many of these come with undesirable side-effects and doesn’t get to the cause of the issue.

If you are having problems breathing without an apparent reason such as the common cold or flu, visit your healthcare provider to rule out any underlying medical conditions that might be causing your symptoms.

If you keep getting rhinitis or sinusitis that is causing shortness of breath, it’s time to take a look at your eating habits. This is where following an elimination diet under the guidance of your doctor can be highly beneficial in relieving symptoms. For example, one study showed that eliminating “trigger” foods alleviated sinusitis in 89% of participants, and asthma and rhinitis in 72% of participants.

To follow an elimination diet, it’s necessary to keep a food journal in which you record everything you consume and what symptoms you experience. If you have a food intolerance, a link will show between an ingredient and one or more symptoms.

16. Anxiety and depression

Millions of people around the world suffer from anxiety or depression, and the causes vary from situational to chemical. The role of diet on our health cannot be underestimated. In recent times, science has been paying closer attention to the relationship between the brain and the digestive system.

It turns out that the digestive system produces 90% of the serotonin produced by the body. Serotonin is a hormone that makes us feel happy, and many anti-depressant medications focus on restoring the balance of serotonin in the brain. But what about the role of the gut?

Another fascinating finding is that the brain and the gut contain 30 identical neurotransmitters. These chemicals, of which serotonin is just one example, carry messages around the brain and the body. They are also responsible for how we feel. It follows, then, that if we have an unhappy digestive system, we’re likely to feel depressed. Interestingly, scientific studies have found gastrointestinal inflammation in a large number of people suffering from depression.

This inflammation is one of the main overarching symptoms of food intolerance, which can be linked to depression. That relationship goes both ways. A depressed mind influences the gut and vice versa.

17. Irritable bowel syndrome

Although people with Irritable Bowel Syndrome (IBS) are sensitive to food, few people with this disorder have a food allergy. Between 3-20 percent of people in the U.S. suffer from IBS symptoms, women more than men.

Some people experience minor symptoms, but others’ symptoms are so severe that they disrupt daily life. Also known as spastic colon, irritable colon, mucous colitis and spastic colitis, IBS is not the same as inflammatory bowel disease and is not related to other conditions of the bowel.

IBS is a cluster of symptoms that usually occur together, and which vary in duration and severity from person to person. IBS symptoms include diarrhea, constipation (often alternating), bloating, gas, abdominal pain, cramping and discomfort.

Food intolerances linked to IBS include dairy foods, beans and pulses, indigestible sugars, fried foods, processed foods and cabbage. Sometimes, chamomile, peppermint and ginger can help to reduce symptoms.

18. Food aversion

People with an aversion to a particular food or drink might feel ill if they think about consuming the substance and might find it virtually impossible to take a mouthful of it as they believe it will make them sick. But the problem is psychological. The person believes that a particular food will make them ill, causing them to develop actual physical symptoms.

Food aversion is a psychological food intolerance wherein a negative physical reaction is associated with ingesting food. A psychological food intolerance has symptoms similar to real food intolerance, but the reactions are psychosomatic.

Some people with a food aversion might develop hyperventilation syndrome in response to food to the extent that they lose consciousness.

19. Milk and yogurt upset your stomach

If you experience gastrointestinal or other symptoms after consuming milk or yogurt, you might be lactose intolerant. Lactose is the natural sugar in milk. To digest lactose, we require adequate quantities of the enzyme lactase. The trouble is, early humans lacked this enzyme and were unable to digest milk products.

An estimated 65% of humans struggle to digest lactose and milk products after infancy. This rate of intolerance is much higher in some areas of the world, with the rate as high as 90% in people of East Asian descent.

Symptoms differ in severity from person to person, but lactose intolerance usually manifests as gastrointestinal symptoms that are similar to those of IBS, namely cramping gas, bloating, diarrhea or constipation, and abdominal pain. The most obvious solution is to avoid milk products, but read product labels carefully as milk sneaks into thousands of products.

20. Underactive thyroid (hypothyroidism)

The thyroid gland is a vital hormone gland. It is butterfly-shaped and lies at the front of the neck. The thyroid gland is essential role in human development, bodily growth and metabolism. It helps regulate many of the body’s vital functions by releasing a steady stream of hormones into the bloodstream. Thyroid hormones are wholly or partially responsible for body temperature, moods and energy levels.

When your thyroid is not producing enough hormones, you develop hypothyroidism. This leads to various symptoms, such as sleeping problems, fatigue, depression, cold sensitivity, and constipation. Sometimes, food intolerances can play a role in an underactive thyroid.

Finding out if you have a food intolerance if you have hypothyroidism can be severe because symptoms can be similar. For example, if you have a gluten intolerance, you might experience bloating, fatigue and depression, which mimic hypothyroidism.

21. Caffeine sends your system into overdrive

We all know caffeine is a stimulant. That’s probably why it’s one of the world’s most popular beverages. But caffeine is not everybody’s cup of tea.

Being caffeine intolerant is possible. How your body reacts to caffeine differs from person to person, and one of the primary reasons for that comes down to your genes.

Doctors offer genetic testing for caffeine sensitivity. If, for example, your body metabolizes caffeine slowly, you might experience significant discomfort if you drink a strong cup of coffee. Symptoms can include sweating, increase in blood pressure, and digestive distress.

With regular consumption, there is an increased risk of heart disease. So, if your system goes into overdrive if you consume something with caffeine in it, try choosing herbal teas that are naturally caffeine-free.

22.You always feel exhausted in spite of sleeping well

If you are still exhausted, mentally/emotionally and physically, you might suffer from chronic fatigue syndrome. This disorder involves severe, long-term fatigue that negatively impacts on the person’s ability to function in everyday life. Between 1-4 million Americans suffer from the condition. Less than 20% are diagnosed. The trouble is that the scientific community does not fully understand the causes of chronic fatigue syndrome.

That said, food intolerance has been a suspect for a long time. Some believe food intolerance is a trigger for the disorder. It can combine with other triggers such as genetics, stress and inflammation.

There is no list of specific foods related to chronic fatigue syndrome. And to make matters worse, foods that might give you a temporary “‘lift” might be the very ones that cause the fatigue a day later.

23. You run to the bathroom all day

If you avoid certain events or places because the bathrooms aren’t great, you might be suffering from food intolerance. This kind of thinking is relatively common in someone with strong food intolerance. The first symptom to strike after ingesting the offending ingredient comes in the form of digestive distress.

Rushing to the bathroom several times a day is common in people with food intolerances. Symptoms include bloating and gas, diarrhea, abdominal pain, all symptoms associated with irritable bowel syndrome (IBS).

One of the culprits responsible for this condition is FODMAP foods. FODMAP is short for Fermentable oligo-, di-, mono-saccharides and polyols. This is a collection of short-chain carbohydrate molecules that the body cannot absorb well.

If you have gastrointestinal symptoms, FODMAPs can bring on diarrhea or constipation, wind, bloating and abdominal pain. A low FODMAP diet has proved successful in relieving gastrointestinal symptoms in a majority of IBS sufferers.

24. Enzyme deficiencies

If we don’t have the right digestive enzymes in the right quantities, we might develop a food intolerance. After we have chewed our food, digestive enzymes break down the larger food particles into smaller molecules. This process begins taking place in the mouth while we are chewing our food. It then continues in the stomach, where stomach acids and enzymes act upon the smaller pieces of food.

It continues in the small intestine, where tiny pieces of food pass through the gut lining and enter the bloodstream. The food we eat contains three macro-nutrients: proteins, carbohydrates and fats. Milk contains all three. The enzyme lactase is not present in people who are lactose intolerant, so milk sugars (lactose) can’t be absorbed. This produces gas, cramping, diarrhea, constipation and bloating.

25. Itchy skin

A familiar sensation many people feel when they eat food they’re intolerant to is itchy skin. This can also be a sign of many other conditions, such as eczema or hormonal changes. To differentiate different types of itches, you have to check how does your skin respond to scratching.

If the itch feels like it’s under the skin, food intolerance might be the cause of your problems. The important thing is to stay calm and not panic.

Be sure to alert your doctor if you can’t get rid of the itch. Before you do anything, it’s important to know that scratching too much won’t make matters any more comfortable. Control yourself and be sure not to injure yourself.

A mild or cold shower can reinvigorate you and allow other sensations to overshadow the itching feeling. Wait for a day or two and think about what could have possibly caused the itch. Experiment and conclude.
