What Are The Symptoms Of Caffeine Allergy

You Feel A Bit Uneasy

Are You Aware Of Your Caffeine Allergies? Here Are The Top 20 Symptoms

If you’re intolerant of caffeine, Hutlin says you might “develop an uneasy, nervous feeling” after drinking caffeine due to the way it affects your brain. Referred to as derealization, this side effect can make you feel a bit disassociated, and usually happens after drinking large amounts of coffee. But it can happen in smaller doses for sensitive people, too.

So if that’s the case, you might want to decrease your caffeine intake, to see if that helps. While most people don’t experience unpleasant side effects after drinking coffee, these symptoms might indicate that you’re sensitive to caffeine, and need to cut back.

Making Sure You Treat Your Body Right

When it comes down to it, youll need to make sure that your coffee isnt hurting your health. No matter how good it tastes, your morning cup of joe isnt worth any long term health effects. Whether you have a full blown coffee allergy or just a mild caffeine sensitivity, its important to make sure that your coffee fits into a healthy lifestyle.

What Is Caffeine Sensitivity And Why It Is Important To Carry Out The Test

To explain what caffeine sensitivity is, we need to examine the causes. These can be attributed to the CYP1A2 gene. Normally, each person should have two copies of this gene, one inherited from the father and the other from the mother. Caffeine sensitivity occurs when one of these two copies is not present or is inactive so causing much slower metabolism of coffee.

Finding out whether someone is caffeine sensitive or is predisposed to coffee intolerance is not easy, as the symptoms are nonspecific that is to say, they can also be attributed to other disorders. These are generally headache, anxiety, difficulty concentrating, nervousness, fatigue and generalised muscle pain.

Symptoms Of Too Much Caffeine Vs Allergy Symptoms

Allergies may be confused with the symptoms caused by having too much caffeine or sensitivity to caffeine. Many people who get sick from drinking coffee are simply seeing the effect of caffeine sensitivity.

Typically, the recommended caffeine consumption for adults is limited to 400 milligrams per day. This is around 4 small cups of home-brewed coffee. After that, many people will start experiencing symptoms.

People who do not have caffeine regularly, or those that are sensitive to caffeine, may experience symptoms after relatively small amounts of caffeine, such as 1 cup of coffee or tea. If a person is not used to caffeinated drinks, symptoms may occur because their body is not used to caffeineâs effects and struggles to process and eliminate the caffeine from the system.

Too much caffeine is associated with similar symptoms to those of a coffee sensitivity. In addition to these symptoms, too much caffeine in someone who is caffeine-sensitive may cause symptoms, such as:

Although very rare, it is also possible to be allergic to caffeine itself. Some people may experience allergic reactions to the compound, which can lead to anaphylaxis.

Any new symptoms should be reported to a doctor or allergist immediately to discuss a plan of action.

How Can You Treat A Caffeine Allergy

How To Determine Caffeine Sensitivity

If you experience physical symptoms of a caffeine allergy, stop ingesting any food or drink that might contain caffeine and contact your doctor right away. Your doctor may advise you to take an over-the-counter antihistamine which may reduce symptoms such as itchiness, swelling, and hives. But the only way to prevent a caffeine allergy is avoiding foods and drinks containing caffeine.

Its important to read food and drink labels.

If you rely on caffeine for an energy boost, consider other ways to naturally boost your energy and stay alert. For example:

Increase physical activity

Start a workout routine and exercise for a minimum of 150 minutes each week. Jog, walk, ride a bike, or take a workout class.

Get plenty of sleep

Sleeping less than seven to nine hours a night can cause morning fatigue. Create a comfortable sleep environment and establish a regular bedtime routine. Turn off the TV and other electronic devices, and make sure your room is a comfortable temperature and dark.

Take vitamin supplements

Some vitamins can naturally boost energy levels over time. These include B vitamins, tyrosine, and rhodiola rosea. Talk to your doctor before starting a vitamin regiment, especially if youre taking prescription medicine.

As said earlier, coffee contains histamine which could trigger an allergy in your body, but the allergy caused by histamine is not the typical allergy we know of. It is instead an inflammatory symptom which could be very severe in specific individuals. Some people suffer from a condition called mast cell activation syndrome, which makes them more sensitive to histamine in food, thus resulting in food intolerance and subsequent release of more histamine in the body.

You Really Really Have To Pee

Caffeine can also affect sensitive people’s GI tract, causing some rather unpleasant side effects. “People who are caffeine sensitive may notice stomach upset when they drink caffeine while others may notice diarrhea,” Hutlin says. “Studies are mixed on why this happens ââ¬â whether it may be a shift in hormones when caffeine is consumed, or other compounds in coffee could stimulate the bowels.”

Some folks also notice an increased need to pee. “Increased urination is another symptom of caffeine-intolerant people because caffeine is a natural diuretic,” she says. “Some people experience more urgency than others.”
