Why Do I Experience Metallic Taste In Cough? Check All Details Here!

Taste is a combination of various sensations that tell the brain what something tastes like.

The taste is the result of the action of thousands of taste buds, the smell, the texture and the temperature.

Someone with a stuffy nose may not be able to enjoy their favorite meal. That’s because an important part in creating that flavor is impaired with the information the tongue sends to the brain.

The brain classifies taste into five basic categories: sweet, sour, salty, bitter, and salty. It is a common mistake that the taste buds only register certain tastes in certain regions of the tongue.

Why do i Smell Metallic Taste in Cough?

There are many factors involved in taste. Taste disorders can result from a number of different conditions or bodily imbalances.

A metallic taste in cough, or dysgeusia, can occur when the body responds to a foreign substance. It can also be a warning sign of other health problems.

Causes Of Metallic Taste When In Cough

There are several common things that can cause a metallic taste in cough. Some may be more serious than others. However, most can be resolved easily or will disappear on their own.

The metallic taste in someone who is healthy is usually not a cause for alarm.

Here Is A List Of Common Causes Behind Metallic Taste in cough:

Poor Oral Health

Those who don’t brush or floss their teeth regularly may experience a metallic taste in their mouths due to gingivitis, periodontitis, or a tooth infection.

These problems can cause people to bleed after brushing or flossing their teeth. Consequently, it can sometimes result in a metallic taste.

These problems can also cause more serious infections of the teeth and gums.

Conditions such as gingivitis, periodontitis and infection of a dental nature require assistance from a dentist.

Good dental hygiene, regular visits to the dentist for dental cleanings will prevent the onset of these problems.

Surgery to remove wisdom teeth can also cause a metallic taste to appear in your mouth.

Sinus Problems

The senses of smell and taste are so closely linked. A sinus infection can impair the ability to taste and cause a metallic taste  .
A stuffy nose is a sign of a sinus problem.
Once the sinusitis has healed, the metallic taste should go away.

These are common problems and usually include:

  • Common cold;
  • Sinus infection;
  • Allergies;
  • Nasal polyps;
  • Other upper respiratory infections;
  • Recent middle ear surgery.

Metallic Taste Caused By Medications

Sometimes prescription drugs can cause an aftertaste as the body absorbs them.

The metallic taste can also arise when the individual feels dry mouth as a side effect of the medication.

Examples of medications that can cause a metallic taste in the mouth:

–  Antibiotics;

–  Antidepressants;

–  Antihypertensives;

–  Medicines to treat glaucoma;

–  Antifungals;

–  steroids;

–  Nicotine patches;

–  Diuretics;

–  Antihistamines;

–  Medicines to treat osteoporosis.

Cancer Treatments

Taste changes are a common side effect of cancer therapies. Such treatments as chemotherapy and radiation to the head and neck.

These treatments can damage the taste buds and salivary glands, sometimes resulting in a metallic taste.

This change is temporary and a normal sense of taste should progressively return.


Vitamins with heavy metals such as copper, zinc or chromium can be the cause of a metallic taste. Prenatal vitamins, iron or calcium supplements can also result in the same problem.

The taste should disappear as the body absorbs the vitamins. However, it is best to check the dosage to ensure that the amount is above the recommended maximum.


Some women report a change in taste and smell early in pregnancy. This happens due to hormonal changes that take place in the body.

Along with a metallic taste, a change in cravings or aversion to certain foods is also common for pregnant women. In this case, the metallic taste tends to fade over time.

Guillain Barré Syndrome

A metallic taste in the mouth can also be a symptom of Guillain-Barré Syndrome.

This is an autoimmune disease that affects the peripheral nervous system.

A  2003 review  – stated that this may be due to dysfunction of small nerve fibers.

A COVID-19 infection

COVID-19 can leave a metallic taste in your mouth. A case study published in May 2020 described a person in China whose first symptom of COVID-19 was a loss of taste and smell. The person described food she normally liked as “bland and metallic.” A few days later, she developed a cough, fatigue, shortness of breath and chest tightness before being admitted to intensive care.

Hay Fever

This is usually tied to a specific season or period of the year. A person may suffer from a metallic taste due to inflamed nasal passages and problems with smelling food.


This is a disturbance of the digestive system, sometimes referred to as dyspepsia. The taste should disappear after improving digestion.


Some people with anxiety report having a bad or metallic taste in their mouth. Anxiety stimulates the release of stress hormones in your body, which can affect your sense of taste. It can also lead to dry mouth, which can contribute to a bad taste.


Multivitamins containing minerals (such as copper, zinc or chromium) or cold remedies (such as zinc lozenges) can cause a metallic taste. Usually the taste goes away as your body processes the vitamins or drugs. Always check the dosage and make sure you don’t take too much.

You Have A Zinc Deficiency Or An Excess Of Zinc

Dysgeusia can be caused by a deficiency or an excess of zinc. Malnutrition, which can include a zinc deficiency, can slow cell turnover, resulting in taste changes. On the other hand, people who take too much zinc can also suffer from dysgeusia – in the form of that annoying metallic taste.

Pine Nut Syndrome Pine

nut syndrome is a rare reaction to pine nuts that starts 12 to 48 hours after eating them. It causes a bitter metallic taste in cough that can last up to a month.


People with dementia often have taste abnormalities, such as the presence of metallic taste.

The taste buds are connected to the brain by nerves. Taste abnormalities can occur when the part of the brain that deals with taste doesn’t work properly.

Exposure To Heavy Metals

If you are exposed to mercury or lead, inhaling high concentrations of these substances can often give you a metallic taste.

Other Allergies

Some allergies cause sinus problems, which can cause a metallic taste in cough. However, there are other allergens that cause a metallic taste. Tree pollen, nuts and shellfish are among these.

Anyone who is not aware of any food allergies, but has eaten or has been exposed to these foods and they have a metallic taste, should inform their physician.

Renal Insufficiency

Kidney failure is one of the most serious causes of metallic taste when coughing. A metallic taste is also quite common in people with diabetes. This condition can also lead to kidney failure.

About 30% of patients with type 1 diabetes and 10 to 40% of patients with type 2 diabetes end up having kidney failure, according to the  National Kidney Foundation.

Waste buildup in the kidneys can result in bad breath or loss of appetite. This condition can be causing a metallic taste in cough.


Diagnosis may involve professionals such as a dentist and an otolaryngologist. Otolaryngology is a medical specialty in diseases of the ear, nose and throat.

Diagnostic steps:

–  Review of the patient’s health history;
