Overview
Taste changes, also called dysgeusia or hypogeusia, are when your sense of taste becomes different than normal. You might notice food tastes bland, metallic, salty, sweet, or bitter in a way it did not before. Sometimes you lose the ability to taste altogether. These changes are usually temporary, but they can affect your appetite and enjoyment of food.
Key facts
Taste changes are common and often go away on their own.
They can be caused by colds, sinus infections, medications, or dental problems.
Your sense of taste works closely with your sense of smell, so nasal issues often cause taste changes.
Yes. Many people experience taste changes at some point in their lives, especially during a cold or sinus infection. It is also very common in older adults and in people taking certain medications.
Taste changes can affect anyone at any age, but they are more common in older adults, people with chronic illnesses, and those who take multiple medications. Smokers and people with poor oral hygiene are also at higher risk.

Upper respiratory infections like the common cold, flu, or COVID-19.
Sinus infections, nasal polyps, or allergies.
Medications such as some antibiotics, blood pressure drugs, antidepressants, and chemotherapy drugs.
Dental problems like gum disease, tooth infections, or poor oral hygiene.
Smoking or chewing tobacco.
Aging – taste buds naturally become less sensitive over time.
Neurological conditions like Bell's palsy, multiple sclerosis, or stroke.
Vitamin or mineral deficiencies, especially zinc.
Risk factors
Being over 60 years old.
Smoking or using tobacco products.
Having a chronic condition like diabetes, high blood pressure, or kidney disease.

When to see a doctor
See a doctor urgently if:
Sudden loss of taste with symptoms of a stroke (face drooping, arm weakness, speech problems).
Taste changes after a head injury or surgery.
Taste changes with severe infection signs like high fever, stiff neck, or confusion.
Book a routine appointment if:
Taste changes that last more than a week or two without an obvious cause.
You are losing weight because food tastes bad.
You are concerned that a medication may be causing the change.
Taste changes that affect your quality of life or mood.

Diagnosis
A doctor will ask about your symptoms, medical history, and any medications you are taking. They may do a simple taste test using small samples of different flavors to see what you can detect.
Tests that may be done
Medical history and symptom review.
Taste test (using sweet, sour, salty, and bitter solutions).
Smell test, since taste and smell are linked.
Examination of your nose, mouth, and throat.
Blood tests to check for infections, vitamin deficiencies, or other health problems.
Imaging tests like a CT scan or MRI if a neurological cause is suspected.
What to expect at your appointment
The diagnosis is usually straightforward. Your doctor will work to find the underlying cause so it can be treated. Most tests are simple and not painful. In some cases, your dentist or an ear-nose-throat specialist (ENT) may be involved.
Treatment
Treatment for taste changes focuses on the underlying cause. Often, the change will resolve on its own once the cause (like a cold or medication) is addressed. Your doctor will recommend the best approach for your situation.
Self-care at home
Keep your mouth clean by brushing your teeth and tongue twice a day and flossing daily.
Rinse your mouth with a mild baking soda and water solution (1/4 teaspoon baking soda in 1 cup water) to help neutralize bad tastes.
Try adding more herbs, spices, and strong flavors to your food, like garlic, lemon, or ginger.
Eat cold or room-temperature foods, which may have less taste than hot foods.
If you can, use plastic or glass utensils instead of metal.
Drink plenty of water and stay hydrated.
If you smoke, try to quit – this can improve your sense of taste.
Medical treatments
If a medication is causing the problem, your doctor may adjust the dose or switch to a different one (only under medical supervision). Treating infections with antibiotics or antiviral medicines can help if a confirmed infection is present. For vitamin deficiencies, supplements such as zinc or multivitamins may be recommended by your healthcare provider. In some cases, oral rinses or saliva substitutes can help with taste changes related to dry mouth.
When is surgery considered?
Surgery is rarely needed for taste changes. It may be considered if polyps, tumors, or other structural blockages in the nose or sinuses are causing the problem.
Living with this condition
Living with taste changes can be frustrating, but small adjustments can help. Focus on making meals appealing in other ways – try different textures, colors, and temperatures. Use marinades, sauces, and seasonings to add flavor without extra salt or sugar. Keep a food diary to see which foods you still enjoy, and eat them more often.
Lifestyle tips
Practice good oral hygiene every day.
Rinse your mouth after meals.
Avoid smoking and alcohol, which can make taste changes worse.
Stay hydrated – drink water throughout the day.
Eat small, frequent meals if your appetite is low.
Diet and exercise
Eat a balanced diet with plenty of fruits, vegetables, and protein. If strong flavors bother you, try bland foods like rice, pasta, or yogurt. If you enjoy strong flavors, experiment with herbs, spices, citrus, and vinegar. Regular exercise can help stimulate appetite and improve overall well-being.
Mental health and emotional wellbeing
Taste changes can make you feel sad, frustrated, or anxious, especially if you lose pleasure in eating. It can affect social situations like sharing meals with family and friends. These feelings are normal. If mood changes persist or worsen, talk to your doctor – they can offer support or refer you to a counsellor.
Prevention
Not all taste changes can be prevented, but you can reduce your risk. Avoid smoking and secondhand smoke. Maintain good oral and dental hygiene. Treat sinus infections and allergies promptly. Let your doctor know if you have taste changes while on a medication – they may adjust the dose early.
Vaccines
Vaccines like the flu shot and COVID-19 vaccines can help prevent infections that sometimes cause taste changes.
Screening programmes
There is no routine screening test for taste changes. Regular dental check-ups and doctor visits can help identify problems early.
Complications
If left untreated
Poor appetite leading to weight loss and malnutrition.
Dehydration from not drinking enough fluids.
Depression or social withdrawal due to lost enjoyment of food.
Incorrect use of salt or sugar (adding too much) which can worsen health conditions like high blood pressure or diabetes.
Long-term outlook
For most people, taste changes are temporary and improve once the cause is treated. If the cause is permanent, such as nerve damage or aging, you can still learn to manage and enjoy food with simple strategies. With the right support, most people adapt well and maintain a good quality of life.
