While many are familiar with feeling nauseous after eating a whole bowl of halloween candy, or feeling tired after thanksgiving dinner - when these symptoms accompany a normal meal, it can be a sign that something is wrong.
Shakiness, dizziness, nausea, and fatigue are all signs that your body is struggling to digest and utilize the food you ate.
The reason behind these symptoms could be a blood sugar issue, a food allergy, or even a parasitic infection.
Finding out what is going on is crucial in stopping these symptoms and ensuring that you are digesting your food properly.
1. Food Sensitivity & Intolerance
The most common cause of symptoms like nausea, racing heartbeat and fatigue is a food intolerance.
Food allergies are generally more serious and can cause symptoms like a numb mouth, severe stomach cramping, swollen tongue or feelings of breathlessness.
Food intolerances (also called food sensitivities) are more common than food allergies and are largely under diagnosed. Usually, the symptoms seem subtle because people have had a low level of inflammation almost constantly for months or years.
Low-grade inflammation caused by food intolerances can lead to symptoms like fatigue, brain fog, weight gain and migraines.

You can do an elimination test and keep a food journal to better isolate the food that you are reacting to.
Often, however, my patients have many underlying sensitivities due to toxin exposure, poor digestion or an autoimmune disease.
In this case, I would order testing so we can quickly isolate the offending foods, remove them from the diet and heal the patient's digestive tract.
A parasitic, fungal, bacterial or viral infection can all cause you to feel sick after you eat food.
In all of these cases, I can order testing to determine if you have an infection and what kind it is.
The strain, type and location of infection within the body will determine the most effective treatment, supplements and therapeutic foods for you.
One of the most common types of infections that produce symptoms after eating is small intestinal bacterial overgrowth or SIBO.
This happens when, due to things like antibiotic use, poor diet or food poisoning, undesirable bacteria overrun the small intestine.

In the case of a parasitic infection, the eggs and larvae can become lodged in your liver and digestive organs, causing symptoms every time you eat.
Many times these types of infection do not have the 'classic' signs of infection like fever and chills. Underlying infections can last for months or years when left untreated.
Lesser-Known Symptoms Of Infection
Stomach pain, cramping
Body temperature regulation problems
Blood sugar regulation problems
In some cases, feeling bad after you eat certain foods can indicate a specific underlying problem. In these cases, the food you are eating is giving fuel to an underlying infection.
