Have you ever had a strange, bitter taste in your mouth, or a taste like you're chewing on a piece of iron, even when you haven't eaten anything? Or do you just have an unpleasant taste in your mouth even when you haven't eaten anything? This is a problem that many people experience, but we don't talk about it much. In medicine, we call this condition Dysgeusia (dys-geus-ya). Don't worry, it's not usually a serious illness. But when you can't taste a food, it's a real pain in the ass, isn't it? Today, we'll talk about it in a simple way that you can understand.
Simply put, what is Dysgeusia?
Imagine that your TV is playing 'Jiri Biri' without being able to tune in properly. The picture is visible, but it's not clear. Dysgeusia is something like that. The taste receptors on your tongue are unable to "report" the taste of food accurately to your brain. This means that the sense of taste is distorted.
This is different from a condition called Ageusia , which is a complete loss of taste. In Ageusia, you can't taste anything sweet, sour, or salty. In Dysgeusia, you can taste things, but they're all wrong . A sweet dish may taste bitter, or a good fish stew may taste like iron. Doctors sometimes call this "altered taste."
What are the main symptoms of dysgeusia?
The way this condition feels may vary from person to person. But there are some common symptoms that can be seen. I have listed these in the table below for clarity.
| Symptom | How you feel |
|---|---|
| Metallic or bitter taste | This is the most common symptom. No matter what you eat or drink, you feel an unpleasant taste, as if you have an iron spoon in your mouth. Some people also experience this as a bitter taste. |
| Change in taste | Food that used to taste sweet no longer tastes sweet. Salted food doesn't taste salty. It's as if the taste system has gone haywire. |
| Good food spoiling | When you eat a dish you love (think chicken curry), it can taste unpleasant, like it's gone bad, like it's rotten. |
| Constant unpleasant taste in the mouth | Even when I don't eat anything, there's just a bad taste in my mouth. It feels like it won't go away even between my teeth. |
Why does this happen? Causes of Dysgeusia
There is not just one reason for this. There could be many reasons. Let's look at the main ones.
Common causes
- Aging: As we age, our eyesight and physical strength decline, and our sense of taste changes slightly.
- Medications: This is a very common cause. Some medications, such as allergy medications, antibiotics, antidepressants, and chemotherapy for cancer patients, can cause changes in taste.
- Poor oral hygiene: Things like not brushing your teeth properly and not cleaning your tongue can lead to an increase in bacteria in the mouth and affect your sense of taste.
- Smoking: Smokers experience a loss of taste and smell over time, and their sense of taste may become distorted.
- Dental prostheses: Dentures that cover the upper palate can sometimes block the taste buds and alter the sense of taste.
Medical Conditions
Dysgeusia can also be caused by certain medical conditions. It is very important to be aware of these.
| Medical condition | How Dysgeusia Occurs |
|---|---|
| Dry mouth (Xerostomia) | This condition occurs when the production of saliva in the mouth decreases due to factors such as not drinking enough water. Saliva is essential for dissolving food and sending it to the taste buds. |
| Severe case of gastritis (GERD) | When stomach acid reaches the throat and mouth, the acidity can damage the taste cells on the tongue and alter the taste. |
| Infections | Viral infections like the common cold, flu, and COVID-19, as we all know, can cause temporary changes in the sense of taste and smell. |
| Pregnancy | Many mothers experience this during the early months of pregnancy. It's due to hormonal changes in the body. There's nothing to worry about, as it usually gets better by the end of the first trimester. |
| Vitamin or mineral deficiencies | Changes in taste perception can occur, especially when zinc or vitamin B deficiency is present. |
| Other medical conditions | Taste changes can also be caused by conditions such as diabetes, hypothyroidism, kidney or liver disease, neurological disorders (e.g. Alzheimer's, Parkinson's disease), and traumatic brain injury. |
How does a doctor diagnose this condition?
If you have these symptoms, the best thing to do is to see your family doctor. He or she will first ask you about your symptoms, the medications you are taking, and any other medical conditions you may have. Then, if necessary, you may be asked to do some tests, such as:
- Smell tests: Smell accounts for about 80% of taste, so this test can be done to see if there is a problem with your sense of smell.
- Taste threshold testing: Tests to see to what extent you can perceive different tastes.
- Blood tests: A complete blood count can be done to check for deficiencies in your body's vitamin levels, sugar levels, and other minerals.
- Imaging tests: Sometimes, if there is a suspicion of abnormal growths or changes in the brain or nerves, the doctor may order an X-ray, CT scan, or MRI scan.
How is this treated?
The most important thing is that the treatment depends on the underlying cause of the condition. There is no one-size-fits-all solution.
For example, if your doctor finds that a medication you're taking is causing the problem, they may be able to change or stop the medication. If it's caused by an infection like COVID-19, your sense of taste will gradually return to normal as the infection resolves.
Sometimes olfactory training therapy may be recommended. This involves exposing yourself to different scents (e.g. lemon, rose, clove, eucalyptus) on a daily basis. Over time, these scents can reactivate the smell memories in your brain and help restore your sense of taste.
Things you can do yourself to reduce your risk and manage your symptoms
While we cannot control some of the factors that contribute to the development of this condition (aging, genetics), there are many things we can do to reduce the risk and make it easier to live with the symptoms.
- Change your food choices: To counteract the iron taste in your mouth, add fruits like lemons and oranges, sour things like pickles, and vinegar-soaked salads to your meals. It's best to cut down on foods that are spicy, high in preservatives, and high in sugar.
- Drink plenty of water: Dry mouth is a big cause of this. So drink plenty of water throughout the day. It is best to drink fluids that are free of sugar or caffeine.
- Reduce your metal usage: Try using glass, plastic, or ceramic utensils instead of metal cutlery and metal water bottles. Some people notice a difference.
- Take care of your oral health: Brush your teeth thoroughly twice a day and clean your tongue. This can help reduce the unpleasant taste in your mouth.
- Rinse your mouth before eating: Dissolve about a teaspoon of baking soda in a glass of warm water and rinse your mouth with that water before eating. This will neutralize the acidity in your mouth and help you taste the real taste of food.
- Suck on ice cubes: Sucking on sugar-free ice cubes and ice lollies can help prevent dry mouth.
- Avoid smoking: If you are a smoker, quitting is one of the biggest ways to help restore your sense of taste.
If you notice that a food has changed in taste, don't ignore it. Don't just ignore it, saying, "This is just a coincidence." Your body may be trying to tell you something. Therefore, it's wise to see a doctor and get advice.
Take-Home Message
- Dysgeusia is not a complete loss of taste, but a distortion of taste (e.g., a taste for bitter food, a taste for iron).
- This can be caused by many things, from simple causes like medications, smoking, and bad oral hygiene to medical causes like diabetes and vitamin deficiencies.
- If you have a sudden or long-term change in your sense of taste, don't ignore it. Be sure to see a doctor .
- This condition often improves when the cause is found and treated.
- Symptoms can be controlled by drinking plenty of water, maintaining good oral hygiene, and making simple changes to your diet.
