Dysgeusia: What is it? Symptoms, Causes, Treatment, Prevention and Home Remedies

The metallic taste in the mouth is a condition in which there is a change in the taste buds.

Occasionally, the person experiences a strange taste in the mouth, which can be unpleasant and persistent. People with this disorder often complain of having a bitter, bad, disgusting or iron taste in their mouths.

Dysgeusia is a distortion of the sense of taste . It is also often associated with Ageusia, which is the total lack of flavor, and Hypogeusia, which is the decrease in taste sensitivity.

Some people with Dysgeusia also have an altered sense of smell. About 75% of the taste sensations come from nerve cells related to smell.

The taste and smell cells work together to produce the sense of taste. Our taste cells can identify four main qualities: acid, bitter, salty and sweet. Subtle aspects of the taste come from its sense of smell.

You may have noticed a bad taste, a change in taste, less ability to taste, or perhaps no flavor in food. Although, a complete lack of taste is rare.

The sense of taste communicates with your brain through your taste buds.

The taste receptors basically only identify the acids, bitter, salty and sweet. Those more subtle aspects of taste sensations actually originate through smell. So, what you may think is a taste disorder, can actually be caused by an odor problem.

Taste disorders go beyond the simple issue of having a problem with it. Taste problems are divided into: Parageusia, Dysgeusia, Ageusia or Hygegeusia.

Parageusia means that you have a bad taste in your mouth. Dysgeusia means that you are going through a change of flavor and that your food can impart a disgusting, salty, rancid or metallic taste.

This change in taste may persist beyond your meal. Dysgeusia is often accompanied by burning mouth syndrome, glossitis or other oral conditions.

When you experience less taste, your taste disorder is known as Hypogeusia. And if it does not detect taste, then the taste disorder is called Ageusia. However, regardless of the type of taste disorder you have, the food you will swallow will not taste right.

Signs and symptoms of Dysgeusia

An alteration in taste or smell can be a secondary process in several disease states, or it can be the main symptom. Distortion in the sense of taste is the only symptom, and the diagnosis is often complicated since the sense of taste is linked to other sensory systems.


Common causes of Dysgeusia include chemotherapy, treatment of asthma with albuterol and zinc deficiency. Different medications may also be responsible for altering the taste and causing Dysgeusia.

Taste disorders, whether described as Parageusia, Dysgeusia, Aguesia or Hygegeusia, can have numerous causes, such as damage to the taste buds, nervous problems, side effects of medications, an infection or other health conditions.

An altered or bitter sense of taste could be due to some diseases. However, daily habits and common conditions that can cause a metallic taste in the mouth include:

  • Dehydration.
  • Breathe through the mouth.
  • Smoke.
  • Dry mouth.
  • The pregnancy.
  • Bilious problem.

Fortunately, many causes of taste disorders are only temporary, curable or correctable. Therefore, you can return your feeling to a familiar taste.

One of the most common causes of a temporary bad taste, a change in flavor, a diminished flavor or a period without taste are infections. Temporary taste disorders often accompany these infectious diseases that cause health problems:

  • Sinusitis
  • Influenza.
  • Pharyngitis.
  • Streptococcal pharyngitis .
  • Infection in the ear.
  • Common cold.
  • Nasal infection
  • Oral infection by fungi.
  • Respiratory infection.
  • Infection of the salivary gland.

Some other health-related causes to create taste distortions are:

  • Uremia.
  • Allergies
  • Dry mouth.
  • Depression .
  • TIA, stroke.
  • Bell’s palsy
  • Tumor cerebral.
  • Nasal polyps .
  • Renal insufficiency .
  • Mastoidectomía.
  • Dental extraction
  • Sjogren’s Syndrome .
  • Migraines .
  • Chemical products, insecticides.
  • Hydroelectrolyte imbalance.
  • Aging, decrease in taste bud.
  • Smoking cigarettes, smokeless tobacco.
  • Ear, nose, mouth or throat surgery
  • Cranial trauma, head injury, concussion.
  • Poor oral hygiene, oral bacteria, bad breath.
  • Hormonal changes; pregnancy, menopause.
  • Vitamin, mineral deficiency; Vitamin B12, zinc.
  • Radioactive iodine therapy; Treat thyroid cancer.
  • Cancer treatment; chemotherapy, radiotherapy.
  • Metabolic and endocrine disorders; diabetes, thyroid disease.
  • Dental problems; caries, gingivitis, periodontal disease, dental abscess.

The drugs are notorious for causing taste changes, bad taste, reduced taste or no flavor. Here is a sample of some drugs that alter the taste and what they mainly treat:

  • Warfarin ; blood clots.
  • Some medicines for HIV / AIDS.
  • Lithium; stabilize the mood.
  • Venlafaxine; depression
  • Propafenone; arritmias.
  • Alendronato; osteoporosis.
  • Many drugs for the treatment of cancer.
  • Metformin; diabetes, obesity.
  • Attacks of topiramate; obesity.
  • Olopatadine; allergic pink eye.
  • Morphine; severe analgesic
  • Antibiotics; bacterial infections.
  • Dihydroergotamine; migraine headaches.
  • Chlorhexidine; Mouthwash for gum disease.
  • ACE inhibitors; hypertension , heart failure.
  • Antihistamines ; inflammation, allergic reaction, allergies.
  • Chlordiazepoxide and clidinium bromide; ulcers, IBS.
  • Combination of captopril and hydrochlorothiazide; high blood pressure
  • Combination of dorzolamide and timolol; eye conditions, including glaucoma.

Treatment for Dysgeusia

Due to the variety of causes of this condition, there are many possible dental treatments that are effective in relieving or eliminating the symptoms of Dysgeusia.

Some other treatments include artificial saliva, pilocarpine, zinc supplements, alterations in drug therapy and alpha lipoic acid.

It depends on the cause, sometimes, the problem disappears once it is eliminated. This can occur if the cause is a gum disease, plaque, a medication you are taking for a short time, or a short-term condition, such as a cold.

If the cause is a yeast infection, the Dysgeusia should disappear after the yeast infection is treated properly. In some cases, for example, if nerves have been damaged, Dysgeusia may be permanent.

Be sure to visit your dentist if the taste changes last at least two weeks. Many times, Dysgeusia will last only a few days if it is caused by a cold or other short-term problem.


Some causes of Dysgeusia can be prevented, but the vast majority do not.

Quitting smoking will improve your sense of taste and smell. Practicing good oral hygiene and receiving regular dental care can also be useful.

Consequences of the Dysgeusia

Alteration of taste for Parageusia, Dysgeusia, Ageusia and Hygegeusia can cause health consequences, such as eating too little, which leads to unhealthy weight loss and malnutrition.

Flavor changes can also be a sign of disease, as is sometimes the case with Parkinson’s disease, Alzheimer’s disease and diabetes mellitus . For great bad seizures, the change in taste is usually a warning sign that one is on the way.

Metallic taste during pregnancy

Does it look like he’s been sucking pennies while he sleeps? This is what you need to know about that metallic taste in your mouth during pregnancy and how to make it go away.

Pregnancy can affect almost any part of the body, and your palate and taste buds are no exception. Many pregnant women report having a bitter or metallic taste in their mouths as one of their pregnancy symptoms.

The change in your sense of taste, known as Dysgeusia in medical terms, may persist even when you are not eating.

When does that metallic taste begin during pregnancy ?:

That metallic taste in the mouth is a common symptom of pregnancy in the first trimester. One study found that an amazing 93 percent of pregnant women reported some change in taste during pregnancy.

How do you feel?

Some mothers have compared it to the taste of spare change or drinking water from a metal cup. Others say it is more of a sour taste even when they do not eat anything to unleash it. While it is difficult to put into words exactly what experience is like, it is recognized when it happens.

What causes metallic taste during pregnancy?

Dysgeusia is caused by changes in hormone levels during pregnancy. Pregnancy hormones, particularly estrogen , seem to play a role in controlling and moderating the sense of taste.

In addition, the senses of taste and smell are intimately connected, so the changes related to pregnancy in the sensitivity of the nose can also lead to that metallic taste during pregnancy.

All this activity in the mouth means that pregnancy hormones are accelerating (although the fact that you never experience this symptom does not mean that your body is not in breastfeeding mode). As your pregnancy progresses and your hormones calm down, the metallic taste should dissipate.

What can I do with the metallic taste when I’m pregnant?

Dysgeusia is surprisingly common in pregnancy. Here’s what you can do to make foods and liquids taste more normal:

Try to banish that metallic taste with acids. Concentrate on bitter tastes like citrus juices, lemonade and, assuming your belly can handle them, foods marinated in vinegar.

All these foods not only have the power to break the metallic taste in the mouth during pregnancy, but also increase the production of saliva, which will help eliminate it.

Talk with your doctor about how to change your prenatal vitamin; some seem to lead to the metal mouth more than others.

Brush your tongue every time you brush your teeth or rinse your mouth with a saline solution (one teaspoon of salt in eight ounces of water) or a solution of baking soda (1/4 teaspoon of baking soda in eight ounces of water) 2 times a day to neutralize the pH levels in the mouth and keep away that spicy taste.

Can I avoid this metallic taste while I’m pregnant?

You can not avoid the metallic taste during pregnancy, but knowing what could happen will help you prepare mentally for this strange but harmless symptom.

How long does the metallic taste last in the mouth?

Like morning sickness, Dysgeusia should improve (or, if you’re lucky, disappear altogether) in the second trimester when those hormones begin to calm down a bit. If not, it should disappear after birth.

Home remedies for metallic taste in the mouth

Dysgeusia is often related to ageusia, a condition in which there is a complete loss of taste and hypogeusia, a condition in which there is a significant decrease in taste sensitivity.

Fortunately, this problem can be solved. The home remedies for metallic taste in the mouth listed in this article are effective, natural and safe.

Lemon and black gram leaves:


  1. Get some fresh lemon leaves.

  6. Consume with food (perhaps, rice) often to reduce the metallic taste in the mouth.
How does it work?

Lemon leaves: natural acidic foods such as lemon help neutralize the metallic taste in the mouth naturally. This is due to the presence of citric acid in them. It eliminates the bad taste in the mouth and keeps it healthy once more.

Black Gram: Scientifically known as Vigna mungo, black gram or black lentils is one of the best home remedies to eliminate metallic taste in the mouth.

Its antioxidant properties help activate the taste buds, while the antimicrobial properties kill germs and prevent inflammation of the tongue.

The remedy is not good, if:

  • You have canker sores Citric acid in lemon leaves can worsen the condition.
  • There are no known side effects of consuming black gram. However, some say it causes flatulence.

  4. Continue for a few days to get rid of the metallic taste in your mouth.
How does it work?

Pinnata Spondias leaves: They are enriched with an abundance of natural phenolic compounds and flavonoids, which exhibit antioxidant and free radical scavenging properties.

Baking soda: 100% sodium bicarbonate is found naturally in mineral springs. This compound has a very mild abrasive action, which helps to freshen the breath, remove the plaque and deodorize the teeth.

Sal: when it comes to maintaining a healthy oral hygiene, salt has always been preferred. In fact, a salt water mouth rinse has been practiced for centuries.

Raw salt is made up of sodium chloride, which not only restricts bacterial growth in the mouth but also helps to neutralize the acids, thus helping to get rid of the taste of the metal.

Green tea: herbal tea is full of antioxidants, which help fight bacterial infections and control inflammations. Green tea is well known for its bitterness, natural stimulating effects and characteristic flavor.

The reason why it is the best remedy to decrease the taste of iron in the mouth is due to the presence of chemical substances, known as catechin polyphenols (or tannins).

These contribute to astringency and bitter taste. In addition to helping a person to eliminate the metallic taste in the mouth, green tea prevents cavities, maintains adequate health of the gums, delays oral cancer and maintains general hygiene of the mouth.
