Have you ever had painful abdominal pain or felt lethargic and sick after eating something sugary? You are not just one. But are they the symptoms of a sugar allergy or something else?
In many cases, the feeling of lingering aftertaste is really just a " sugar-canker " that occurs when you eat one ton of sugar thanks to the immediate strain on your blood sugar levels you can crash and burn , But some people are very sensitive to a smaller amount of sweet sweetener.
Yes, you may be sugar-incompatible – or even a true sugar allergy, in very rare cases. It sounds extreme, but different types of sugar can definitely affect people, experts say. "Sugar as a substance has a real impact on people, psychologically and physically," says New York City-registered dietitian Jessica Cording versus SELF.
And there are actual symptoms of a sugar allergy or intolerance. So keep reading to know the signs you need to watch out for.
The symptoms of a sugar allergy usually occur immediately.
People with a true sugar allergy usually have immediate physical symptoms that are similar to those of other food allergies. According to the graduate nutritionist Lisa Moskovitz, RD, CEO of the NY Nutrition Group these include:
But there is one Difference between a food allergy and a food intolerance.
Everyone has certain foods that simply do not sit with them or cause symptoms that are not as desirable as indigestion, bloating, or cramping. This does not necessarily mean that you have a real allergy to this food or ingredient. And while some use the terms interchangeably, food allergy and food intolerance are actually two different things. Here is the difference:
Food Allergy: This is a reaction that occurs when your immune system overreacts to a food protein and believes that it is a harmful substance. Food Allergy Research & Education FARE).
The symptoms of food allergy may be mild to life-threatening, says FARE, and may include:
- abdominal pain or cramps
- ] difficulty in breathing  Anaphylaxis
Food Intolerance: If you have an intolerance to a food or an ingredient, you have difficulty digesting whatever that food is. In general, food intolerance leads to digestive problems and the symptoms are not as severe as food allergy, says the Mayo Clinic .
There are several reasons why you might be intolerant of a particular food. Sometimes the result is that your body does not produce any enzyme necessary to break down this diet (for example, if you have lactose intolerance, you will not have the enzyme lactase needed to break down lactose, the sugar in the milk). In other cases, it has an underlying health status, such as the Irritable Bowel Syndrome (IBS) or even stress or anxiety, says the Mayo Clinic .
According to the American Academy of Allergy, Asthma and Immunology (AAAAI), the symptoms of food intolerance include:
- intestinal gas
- abdominal pain
Es is easy to confuse the two due to the symptoms may overlap (eg, diarrhea, abdominal pain). One major difference, however, is that food intolerances are not the result of a immune system disorder. In addition, people with food intolerances may be able to eat a small amount of food without any problems (or they may help with the digestive aid), whereas in general, allergy does not cause any food allergen.
Intolerance of sugar is more common than a sugar allergy.
Normally people are not tolerant of certain types of sugars, says Moskovitz. Those with a sugar intolerance can only have the above-mentioned gastrointestinal symptoms, possibly in addition to fatigue, some time after eating the sugars for which they are sensitive, she adds.
These are the major sugars that may cause intolerance or sensitivity
Fructose is found naturally in foods such as fruits, some vegetables, honey and some fruit juices, says the Mayo Clinic . It is also present in table sugar as well as corn syrup with high fructose content.
This is a sugar found in milk and other dairy products. If you are lactose intolerant, you will not be able to digest lactose properly so you get those unwanted GI problems. (As a reminder, this is not the same as a milk allergy which means that your immune system responds to the proteins in the milk.)
Sucrose is from cane (19459006) and is the guy who makes table sugar.
You've probably seen ingredients such as erythritol or xylitol on food labels. These are actually sugar substitutes that are used in many low-calorie or sugar-free foods. However, they are worth something in this regard, as they can cause GI problems for many people. In rare cases, they can also cause allergic reactions, as [SEL] already reported .
However, in some cases it can not be sugar alone.  "If anyone describes a sugar intolerance, it is most likely an underlying problem compounded by consuming sugar foods," says registered nutritionist Beth Warren, founder of Beth Warren Nutrition and author of  Living with real food .
Instead, the problem could be a microbial imbalance in the gut with an overgrowth of yeast . As yeast feeds on sugars, it may aggravate the problem and cause symptoms such as rashes and swelling, she says.
To alleviate symptoms of sugar allergy or intolerance.
Cases of an allergic reaction to sugar are rare, but they pass . If you have an immediate reaction after eating sugar – your throat feels tense, you have trouble breathing, a rash, etc. – you should consult your doctor or the emergency room. In severe cases, an allergic reaction could progress to anaphylaxis if it is not addressed quickly and early. And if you are not sure at this time whether you suffer from this type of allergy (or whether it is life-threatening or not), it is safer to be on the safe side.
In severe cases, you may be treated with epinephrine (a drug that can reverse anaphylaxis ) and then possibly a steroid (such as cortisone) to reduce inflammation and bring the reaction under control, says FARE . Epinephrine is generally harmless, and even if it's unclear how severe your allergy is, it's safe to use, explains FARE.
If your allergic reaction is milder, you may only need one antihistamine says FARE. From there it may be that your doctor or a allergist / immunologist would like to perform Skin Tear Tests to determine the cause of the reaction and to determine if sugar is actually the cause. If you are diagnosed with a serious allergy to sugar, you may need to carry an epinephrine autoinjector (EpiPen) in emergencies.
If you find you have GI symptoms after eating sugar Because cording seems immediate or severe, Cording recommends cutting out sugar, white bread, white flour, energy drinks, fruit and fruit juices. "Some people cut off alcohol well," she says. It also encourages you to eat a lot of protein and make sure it does not have starchy vegetables, avoiding potatoes and corn (the starches in them will turn into sugar in your body).
Of course you do not have to be so extreme with your diet. Registered Nutritionist Karen Ansel tells SELF that it is a good idea to narrow down what kind of sugar you are allergic or incompatible with. She recommends keeping and recording a food diary, which leads to flickering. "It's quite possible that lactose bothers you, but other types of sugar are not a problem or too many sweets will make you break out," she says. Ultimately, it's really about finding out what your body is responding to and how bad it is.
If you suspect you have a sugar allergy or intolerance, you should consult your doctor.
"Every time you have these types of symptoms, it's really important to get in touch with your doctor to make sure there are no underlying conditions," says Cording.
