Medically, a metallic taste is described as an example of parageusia or dysgeusia which refers to abnormal alterations in the sense of taste. It is a sensory disorder that can either be acute or chronic, depending on the time of development of the problem. A metallic taste can occur as the body’s reaction to the presence of a foreign substance. It can also be a symptom of more serious health complications. Here are some common reasons given below that causes the metallic taste in the mouth.
1. Pregnancy
The different fluctuations in hormone levels that occur during pregnancy can cause you to have a metallic taste in the mouth. It typically occurs during the first trimester.
2. Sinus problems
Your sense of smell is very closely connected to the sense of taste. Therefore, anything that affects your sense of smell, such as sinusitis can also affect the taste sensation. This metallic taste goes away with the infection.
3. Nervous system disorders
Your central nervous system sends and receives information from the other parts of your body. Sometimes there can be lesions in the nerves that control the taste sensation, such as in Bell’s palsy. A stroke in the part of the brain that controls taste can also cause a metallic taste in the mouth. Unfortunately, this is usually permanent.
4. Medication
Some micro-nutrient supplements that contains heavy metals like copper and zinc can lead to a metallic taste in the mouth. Iron supplements can also cause it. Try to make sure you are not overdosing on these supplements. This taste can also be a side effect of taking some antidepressant drugs, antibiotics and medication for cardiovascular conditions.
5. Poor oral hygiene
If you don’t take care of your mouth by brushing regularly, it can result in some dental problems like periodontal disease and gingivitis. These conditions can cause you to bleed from your gums, causing a metallic taste in your mouth. The metallic taste of blood is due to presence of iron in your hemoglobin. You should see a dentist to take care of this issue. Proper oral hygiene can also help you to prevent this.
If you experience this, you should see a health professional to rule out more serious diseases.
