Why do i feel tired and nauseous after eating?

We’ve all been there. You just finished a delicious meal, feeling happy and satisfied, but suddenly you start feeling tired and nauseous out of nowhere. It can be quite uncomfortable and frustrating, especially if it happens often. But why does this happen? Is it something we are doing wrong? Or is our body trying to tell us something? Let’s take a closer look at what might be causing these symptoms.

The food coma phenomenon

Have you ever heard of the “food coma” phenomenon? This refers to that drowsy feeling you get after eating a large meal or one with lots of carbohydrates. Carbohydrates turn into glucose in your body, which then triggers the release of insulin from your pancreas. Insulin helps your cells absorb glucose for energy production. However, too much insulin can cause your blood sugar levels to drop rapidly (low blood sugar alert!), leading to that post-meal fatigue.

In addition to carb-heavy meals, consuming high-fat foods can also contribute to feelings of lethargy since they take longer to digest than other macronutrients such as protein or carbs.

Overeating (aka gluttony)

Okay listen here YOU PIG, overeating is bad news bears when it comes to how you’re going feel afterwards (sorry not sorry). Your stomach has an average capacity of 1 liter/33oz before filling up (Yes okay we use metrics) ; so even though those all-you-can-eat buffets are tempting AF- resist! Eating beyond this limit will stretch your stomach walls until presto – abdominal discomfort enters stage left (cue ominous background music).

Asides from stretching the stomach muscles – let’s remember that digestion requires energy hence more intake equals more work. Having said that…the catch is:-If too much food enters the intestine undigested proteins tend towards decomposition by microbes that produce gas and other unpleasant substances (not to be described in detail…) The gut is just trying its best to break down the food, but overeating can make it harder for your digestive system to do its job. This upset may lead you towards those relaxed puke-moments on your couch or in some more unfortunate instances, at work/in public (empathy alert).

Food intolerances & allergies

Bear with me here folks…food intolerances occur when we lack enzymes necessary for digesting specific ingredients such as lactose or gluten (Please don’t mention veganism) . Allergies are immune overreactions whereby antibodies flag a certain type of protein thus presenting symptoms depending on how sensitive an individual is cue compulsive need two double check ingredient labels. Asides from nausea and fatigue common gastro-intestinal symptoms include bloating abdominal pain and Diarrhea. Remember you’re no alone- there’s more non-dairy milk options than ever before so chin-up my fellow intolers!


Water – natures gift staving off dehydration one litre/quart at a time…especially after our delicious meals.
Ideally, we ought drink water alongside meals giving our body the much-required hydration post-eating. Interesting fact though; thirst often masks itself as hunger hence causing us to mistakingly consume too frequently while ignoring hydration meanwhile consistently drinking carbonated drinks won’t necessarily count twards this quota- sorry Sprite lovers! Failure keeping up water intake leads to headaches/nausea – Don’t let thirst outsmart You – WATER IS THE GREATEST THING- Sorry H2O advocacy moment lol.

Another fun fact: fruits contain high levels of hidden water Quoting apple nutrient director “Crunch into an apple instead of sipping juice”. Not only will eating fruit ensure proper hydration but also lower amounts of sugar compared with processed/juiced varieties.

Gut Microbiome

Colonies of microbial cells present within our gut and sometimes post-meal are responsible for producing compounds which tell us we feel fuller! These bugs act as gatekeepers (pretty cool right?) allowing the nutrients required to enter while preventing harmful pathogens. Sometimes though, either from diet or medication some bacteria isn’t accepted and passes through undigested – this leads again to fermentation via bacteria in the lower bowels coupled with gas build-up hence causing discomfort, lethargy et al…

Fruits and Veg- Should be eating these like its Thanksgiving every day! Not just due one’s general health but also The fact fibrous foods increase bacterial metabolism found within the GI tract mean by consuming them then you’re augmenting a healthy microbiome thereby minimising such symptoms felt earlier on. So if feeling spoilt for choice consider adding more cucumber tomatoes berries legumes into your daily food regimen – Yogurt containing Activa also works wonders!

So next time after having that mouthwatering dish instead of reaching straight towards lying down all day remember food comas are avoidable depending on a change of lifestyle could even begin keeping track via trackers/osmino apps…(Nothing says efficiency than high alert smartphone reminds am I right?).

Have a small exercise routine handy YOU DON’T NEED TO BE Herculean just enough stretch back ties and limbs will get blood flowing sending enough oxygen circulating throughout the body. Don’t forget water consumption both during meals along with activity breaks matters too! With so much going on in our lives outside let’s guarantee ourselves optimum wellness vibes when it comes to mealtimes.
