You will find yourself nauseous after eating what was once your favorite food. It can happen for various reasons, and a few of them can be fatal and require immediate attention. So let’s check what causes a minty taste in mouth.

Oral hygiene

After you eat, digestion starts from your mouth right away. Saliva is your mouth contains enzymes like amylase that break down carbs from your food. Carbs are made with glucose,  sucrose, or starch.

Starch starts to degrade in the mouth into glucose, and the process finishes off in your stomach. However, sucrose stays in your mouth.

Sucrose often sticks to your teeth which are broken down by natural bacteria. These bacteria feed off the sugars and produce lactic acid. This strong acid erodes your enamels and causes a sour taste in the mouth.

If there is more leftover food in your teeth, bacteria destroy it to produce malic acid and give a more spicy foul taste in the mouth. Excess acid produced in the mouth can also give you a burning sensation at the back of the throat.

Stress on brushing more frequently, and make sure to clean your tongue thoroughly. Use antibacterial mouthwash to ensure there are no food leftovers in your mouth.

7 Reasons Why You Experience Metallic Taste in Mouth – Dr.Berg

Acid reflux

Are you getting a minty tingling taste in your mouth just after eating? Don’t worry; you’re not going insane. It happens with almost everyone.

When food enters your esophagus and approaches your stomach, it produces gastric acid to digest the food. There are thin muscles at the lower end of your esophagus to ensure that the food sent to the stomach doesn’t come back up.

However, sometimes it is dysfunctional and lets some of the food back up along with the acids produced by the stomach. This causes gastroesophageal reflux disease or GERD. Too many gastric acid secretions mean too much saliva secretion. This gives a sudden minty taste to mouth.

Make sure to stay well hydrated and eat slowly in smaller amounts. Avoid foods like hot coffee or excess spicy foods. Don’t lie down immediately after eating and try different combinations of foods to see what is best suited for you to avoid getting symptoms of GERD.

If you’re still getting a weird minty taste in mouth or throat irritation, omeprazole might help but you might want to check with your health practitioner for full discretion.

Phantosmia is the reason you don’t feel like eating, even if you’re given your most favorite food. Food that was once very pleasant to taste becomes foul-tasting.

Although the reason behind this is still unknown, some studies have shown that coronavirus is not directly related to loss of taste since taste buds don’t have the receptor to bind to the virus. However, the release of chemicals causing inflammatory reactions in the body gives a foul taste in the mouth.

To know if you’re infected, get yourself tested first. Don’t be afraid that the result doesn’t come in your favor. Isolate yourself and just follow your doctor’s advice. You will soon find the minty taste in mouth coronavirus is disappearing.


The most common complaint of pregnant women in their first trimester is that their mouth tastes like chewing on metal coins. This happens because your hormones are on a roller coaster ride, especially your estrogen.

Usually, the foul taste goes away as the pregnancy progresses, but it can sometimes stay throughout your pregnancy. As your uterus size increases, it puts pressure on your stomach, causing GERD.

Uncontrolled diabetes causes a complication called diabetic ketoacidosis. Diabetic ketoacidosis occurs when there is insufficient insulin to burn carbohydrates, so your body burns fat to get energy. Burning fat is known as ketosis.

As a by-product of ketosis, a chemical called acetone is produced, which is excreted from the body through your breath. Acetone is responsible for the sweet minty taste in the mouth during ketosis.

Diabetic ketoacidosis is more common in type 1 diabetics since it occurs in children who are unaware they have developed diabetes. So if a child has sweet breath, you may need to take your child to a doctor immediately.
