Can you get sick from eating too much?

In this brief guide, we will provide an answer to the query, “Can you get sick from eating too much?”. Additionally, we will review the harmful effects of overeating and some ways to stop eating too much.

Can you get sick from eating too much?

The answer is yes, you can get sick from eating too much if you are doing this regularly. However, eating more than usual occasionally does not cause much harm. 

If you eating too much that means you are consuming a high-calorie diet, which in long term can pose a potential health risk leading to gastrointestinal problems, obesity and diabetes.

Symptoms of overeating

If you are consuming a high-calorie diet for a longer period of time, you will experience symptoms such as bad breath, increased acid reflux disease, decreased focus, loss of memory,  increased levels of facial oils leading to acne.

Harmful effects of eating too much 

When we eat more, our bodies have to work harder to digest the food, this leads to various health problems, including: 

  • Obesity and unwanted weight gain: If you are eating too much, for a longer period of time, it can cause excessive accumulation of fats in your stomach by slowing down your digestive process leading to unwanted weight gain, obesity and other health problems including arthritis, high blood pressure, sleep apnea.
  • Diabetes: If you are consuming a high-calorie diet and not spending regularly, it can lead to diabetes- a disease that necessitates lifetime medication. If you are diabetic, eating too much can make your blood sugar levels harder to control. 
  • Sleep disturbances: People who eat too much can suffer from sleep disturbances as they stay awake to overcome their cravings and to indulge in creating possibilities to eat. 
  • Increase the risk of cardiovascular diseases: Overeating can deliberately increase the risk of cardiovascular diseases. That is due to the secretion of the stress hormone- norepinephrine, which causes an increase in blood pressure and heart rate. 

People who are already diagnosed with cardiovascular diseases are more vulnerable to developing severe heart risks from overeating.

  • Gastrointestinal issues: Eating a high-calorie diet for a longer period of time can take a toll on your digestive system. You may suffer from health problems like excessive gas and bloating, acid reflux and inflammatory bowel syndrome.
  • Heartburn: To break down the food into a digestible form, our stomach secrets hydrochloric acid. If you are eating way too much, more hydrochloric acid is secreted into your stomach which moves up into your food pipe, leading to acid reflux and heartburn. For this reason, avoid foods that are loaded with fats. 
  • Poor brain function: Overeating leads to impaired brain functioning as large quantities of fat intake lead to memory problems, and decreased mental capacity. 
  • Nausea: People who eat a high-calorie diet on a regular basis, often suffer from symptoms of indigestion and nausea. Eating more than your body’s capacity to effectively digest, may also trigger vomiting- the body’s natural mechanism of alleviating stomach stress. 
  • Fatigue: If you are eating too much you may experience fatigue and tiredness at all times. That is due to a process termed reactive hypoglycemia, in which your blood sugar levels drop right after you consume a high-calorie meal. This will, in turn, make you feel sleepy, tired and low on energy.

What to do if you ate too much? 

If you have eaten too much, pull yourself away from the table, burn down your calories by engaging yourself in some work, for example, clean the dishes or engage yourself in some deep breathing exercises. 

Ways to stop eating too much

  • Keep a check on your calorie intake. This helps you to stop eating when you have reached your daily calorie intake. 
  • Try to chew your food slowly and properly so that your body can easily digest it. 
  • Eat foods that are rich in fibre as these foods make you feel full for a longer amount of time 
  • Consume a healthy diet, for example, by adding a large portion of protein-rich foods to your diet. This reduces the secretion of the hunger-regulating hormone- ghrelin
  • Drink water in between, before and after consuming meals. 
  • Do not get yourself distracted while eating. Keeping yourself focused on your food will allow you to be more aware of the amount you are consuming. 
  • Eat more salads, fruits and vegetables that will keep you full. This way, you will not eat in between your meals. 
  • Try not to skip meals as skipping meals can increase your cravings and in turn, you will eat more.
