Taste is something that many of us do not spend a lot of time thinking about. However, if one develops a disorder that affects their taste, then they will likely try to do anything to get it back. Dysgeusia is a common taste disorder. It is a condition that causes everything to taste metallic, sour or bitter. The good news is that there are ways that this condition can be treated.

Symptoms of Dysgeusia

You will notice a difference in the way that food and drinks taste. You may find that certain food tastes less salty or sweet than others. You may also find that certain foods taste more metallic, rotten or sour. Additionally, you may suffer from a condition called burning mouth syndrome. This is a condition where you feel a burning, painful sensation in your mouth.

What Can Cause Dysgeusia?

It isn’t uncommon for someone to suffer from dysgeusia. There are several things that can potentially cause this condition.

Certain Medications

It is common for people who take certain medications to have a metallic taste in their mouths. In fact, there are 200 known medications that can cause dysgeusia. Ace inhibitors, diuretics and antibiotics are some of the drugs that can cause you to experience a metallic taste in your mouth.

Cancer Treatment

Dysgeusia can sometimes be caused by radiation or chemotherapy treatments. These treatments can sometimes interfere with your sense of taste permanently. If you are receiving cancer treatments, then it is a good idea for you to talk to your doctor about the side effects that you are experiencing.


It is common for type 2 diabetics to have tongue dysfunction. This is a condition that is referred to as diabetic tongue. Many diabetics notice that their taste changes frequently throughout the day. This problem may be caused by blood sugar fluctuations.


If you have a fungal, viral or bacterial infection, then this can cause your tongue to swell. Blood flow to your taste buds is also reduced. Additionally, your body can also create chemicals that change the way that you taste.

Vitamin Deficiencies

If you are low in zinc and Vitamin B12, then you may notice a change in your taste.

Other Possible Causes

Autoimmune diseases, pregnancy, head injury, tobacco use and menopause can change the way that you taste.

Ways to Treat Dysgeusia

The best way to treat dysgeusia is typically treating the problem that caused it. For example, if your problem is caused by a vitamin deficiency, then you can take supplements. You can also quit smoking if tobacco has caused you to experience a change in your taste. Additionally, if you have a medical condition, then you need to get it treated.

You can also talk to a dietitian. They can show you how to use flavorings and spices to enhance your food. Furthermore, you will need to see a dentist at least twice a year. Your dentist will make sure that your teeth and gums are in great shape. They will also make sure that you are brushing and flossing properly.
