Is Feeling Sick After Eating Sugar A Sign Of Diabetes


Early Signs Of Diabetes

16 Signs Your Blood Sugar Is High & 8 Diabetes Symptoms

Both types of diabetes have some of the same telltale warning signs.

  • Hunger and fatigue. Your body converts the food you eat into glucose that your cells use for energy. But your cells need insulin to take in glucose. If your body doesn’t make enough or any insulin, or if your cells resist the insulin your body makes, the glucose can’t get into them and you have no energy. This can make you hungrier and more tired than usual.
  • Peeing more often and being thirstier. The average person usually has to pee between four and seven times in 24 hours, but people with diabetes may go a lot more. Why? Normally, your body reabsorbs glucose as it passes through your kidneys. But when diabetes pushes your blood sugar up, your kidneys may not be able to bring it all back in. This causes the body to make more urine, and that takes fluids. The result: You’ll have to go more often. You might pee out more, too. Because you’re peeing so much, you can get very thirsty. When you drink more, you’ll also pee more.
  • Dry mouth and itchy skin. Because your body is using fluids to make pee, there’s less moisture for other things. You could get dehydrated, and your mouth may feel dry. Dry skin can make you itchy.
  • Blurred vision. Changing fluid levels in your body could make the lenses in your eyes swell up. They change shape and canââ¬â¢t focus.

Cuts Or Wounds That Are Very Slow To Heal

Its not uncommon for an individual with high blood sugars to get a bruise or cut that just does not heal.

This is particularly common on the extremities that are furthest from the heart, like hands or feet.

Why does this happen?: Sugar lingering in the bloodstream begins to damage the arteries and veins, which restricts circulation. Blood is required to facilitate healing, so limited circulation to a wound or bruise will slow the healing process dramatically.

You’re Always Exhausted After Eating

Take a moment to think about how you feel after eating a sugary meal. If you need a cup of coffee or start to fall asleep at your desk at work, it could be due to wavering blood sugar levels.


“People who process sugar normally and quickly tend to feel energized, satiated, and calm after ingesting sugar,” Dale says. “People who are more sensitive to it feel tired, irritable, and tend to actually crave more sugar, aka the withdrawal/addiction response.”

It’s this craving that’ll send you pawing through your desk, looking for candy or cookies or something to help you get through the rest of the day. And that can be a sign sugar isn’t agreeing well with your body.

Excessive Thirst Is One Of The Classic Early Signs Of Diabetes

Drinking unusually large amounts of fluids throughout the day and even overnight is a glaring symptom.

Intake can be something like 4 litres or more per day. You can even start to feel thirsty immediately after youve just had a drink.


The more you drink, the more you urinate, which feeds back into the excessive urination cycle.

Why does this happen?: This is the bodys response to increased urination. With all that extra fluid loss, you become very dry and thirsty.

  • Put the person in the recovery position and do not put anything in their mouth so they do not choke.
  • If an injection of glucagon is available and you know how to use it, give it to them immediately.

    How Does Illness Affect Blood Sugar Levels

    When you get sick whether it’s a minor illness like a cold or a bigger problem the body sees the illness as stress. To deal with the stress, it releases hormones that increase sugar in the blood.

    In one way, this is good because it helps supply the extra fuel the body needs. But in a person with diabetes, it can lead to blood sugar levels that are too high. Some illnesses cause the opposite problem. If you don’t feel like eating or have nausea or vomiting, and you’re taking the same amount of insulin you normally do, your blood sugar levels can get too low.

    Blood sugar levels can be very unpredictable when you’re sick. Because you can’t be sure how the illness will affect them, it’s important to check blood sugar levels often on sick days and change your insulin doses as needed.

    Also Watch For High Blood Sugar

    If youre not eating due to an acute illness like the flu or an infection, its also common for your blood sugars to rise.

    When you have diabetes and are acutely ill, you should check your blood sugars up to four times per day, drink plenty of fluids and contact your doctor if your blood sugars are consistently over 250, Garvey says.

    If Youre Taking Steroids

    Some conditions, like Addison’s disease, severe asthma, rheumatoid arthritis and lupus are treated with steroids. If you have diabetes, taking high doses of steroids for periods of time can make your blood sugar levels rise. This is called steroid-induced hyperglycaemia. Your doctor or nurse will talk to you about this. They may ask you to make some changes to how you manage your diabetes, so that you can keep your blood sugar levels within your target range.

    Some people with coronavirus are being treated with a type of steroid called dexamethasone. Not everyone with coronavirus will need this steroid its only used in hospital when someone is really unwell and needs help to breathe. It works by reducing the inflammation that coronavirus can cause and supports your immune system to fight it.

    While this works well for treating coronavirus, its not so good when it comes to diabetes. Dexamethasone makes your body more resistant to insulin, making your blood sugar levels go very high. If youre given dexamethasone, you may need insulin to help reduce your blood sugar levels. If you already take insulin, you may need to take more or take a different one that does a better job of bringing your blood sugars down.

    You’ve Been Feeling Emotional Lately

    An unstable mood can be caused, in many ways, by blood sugar fluctuations, which Hershenson says can impact how you feel. Studies have also shown a connection between the intake of sweet foods, beverages and added sugars, and symptoms of depression.

    What you eat really can play a large role in how you feel overall, including mentally and emotionally. While speaking with a therapist will always be a good idea if you aren’t feeling like yourself, it can also help to pay attention to what you’re eating on a daily basis.

    If you’re consuming a lot of sugar, you might notice a big difference if you balance out meals in a way that keeps your blood sugar even. Or by lessening your sugar intake and seeing how that makes you feel.

      How To Eat Sugar And Avoid ‘sugar Hangovers’

      First, you should try to stay in the recommended range for daily intake of sugar, which is about 50 grams of added sugar per day. “You should aim to keep your added sugar intake at 10 percent or less of daily calories. For a 2,000-calorie daily diet that would be no more than 200 calories or 50 grams of added sugar per day,” says Gorin.


      “Besides keeping your daily total sugar intake at or below the 50 grams per day guidelines, you should also avoid eating lots of sugar in one sitting,” she adds. “Spacing out the sugar you eat throughout the day will be easier on your body and blood sugar. Again, combining sugar with other foods that contain protein, fat, and or fiber will also help you feel more balanced.”

      Another tip from Gorin on reducing sugar intake and avoiding a sugar hangover is to make your own dessert at home. This way you can control exactly what goes in your food and there is no guessing about how much sugar you could be eating. “One of the easiest ways to reduce your intake of added sugars is to make your own desserts that don’t contain any added sugars,” says Gorin. “For instance, you can make a homemade ‘nice cream’ or even a chocolate pudding that doesn’t contain any added sugars. These recipes are sweetened naturally with fruit,” says Gorin.

      Sugar Hangovers: Why You Feel Bad After You Eat Sugar

      Crashing after you eat sugar? It’s a common issue that can be avoided with these tips.

      Sugar is the black sheep of the health and wellness world. Whether you love it, avoid it like the plague or fall somewhere in between, sugar is one of the most hotly debated topics in health. A very real, yet perplexing situation, is what I call a sugar “hangover.” No matter what you call it, feeling tired or dizzy after eating sugar can happen, but what does it mean exactly?


      One minute you can be riding a sugar high, and the next you feel just plain gross. Sometimes it happens right away, or has a delayed effect . While you may not get a full-fledged “hangover” every time you eat sugar, even feeling a little bit bad is annoying. To find out why this happens I talked to Amy Gorin, a registered dietician and owner of Plant-Based Eats.

      The Other Jab Kids Must Have

      How Much Sugar is Too Much Sugar: The Bitter Truth

      Last month I wrote that I was worried that thousands of teenagers had missed out on vital vaccines they are supposed to have at school, having spent so much time out of the classroom.

      Official figures showed that uptake of the HPV jab given to year eight students to protect against human papillomavirus were down on the year before.

      I am pleased to report that, from what Im hearing, most pupils have been jabbed by now as part of catch-up programmes for both HPV and meningitis. My teenage son received his last week I do reflect on how incredible it is that we are vaccinating a generation against some of the most horrible cancers that HPV causes.

      If you think your child or grandchild has slipped through the net, and still hasnt had a jab, get in touch with your GP and ask whats going on.

      You Constantly Run Out Of Motivation

      Aside from flagging energy levels, take note if you’ve been lacking motivation lately. “If you feel drowsy and tired after eating a sugar-heavy snack, then you should realize that your body is not burning or storing glucose at the rate you are consuming it,”nutritionist Parker Condit tells Bustle. “In addition to this being a lousy way to live, it’s also an indicator that something is wrong If all you feel like doing is sleeping and lounging around, then it’s time to start being more aware of what you are consuming.”

      It may be that eating a lot of sugar isn’t working for you, and that it’s officially time to consider eating and drinking less of it. It can certainly take some time to get used to the change, and it doesn’t mean you can’t have sugar on occasion. But sometimes the payoff is worth the initial adjustment phase, especially when it comes to your health.
