Dysgeusia (Metallic Taste in Mouth) in Pregnancy: Causes & Remedies

Metallic Taste in Mouth During Pregnancy

Pregnancy can bring many changes in a woman’s life, and fluctuating pregnancy hormones are responsible for most of these changes. Symptoms like morning sickness, swelling in the feet, and pain are commonly experienced by a woman when she is pregnant. But some women may experience a strange, unpleasant metallic taste in their mouth during pregnancy. You might feel as if you are sucking on a rusty coin or chewing on a piece of aluminium foil. This occurrence of a metallic palate during pregnancy is called dysgeusia.

Dysgeusia [dis-GYOO-zee-a] or metal mouth during pregnancy is a harmless condition. The exact reason for dysgeusia is not known, but experts believe that the influx of hormones during pregnancy brings about changes in taste in pregnant women, especially during the first trimester when the body is still trying to adjust to the pregnancy.

What Is Dysgeusia or Metal Mouth During Pregnancy?

A metallic taste in the mouth is an early symptom of pregnancy. The changing pregnancy hormones may trigger certain sensory changes in a pregnant woman that can leave a foul taste in the mouth. Many pregnant women may feel a metallic, burnt, sour or rancid taste in their mouths. Many pregnant women have described the metallic taste in pregnancy as having a mouthful of old coins or lapping on a handrail.

Dysgeusia is a condition in which a person experiences foul, salty, rancid, or metallic taste in the mouth. Dysgeusia will not result in food aversions or cravings during pregnancy, but it can cause the food to taste bitter or leave a bad taste after eating. Sometimes the metallic taste in the mouth in pregnancy may persist even without having eaten anything. Dysgeusia in pregnancy can make the condition of morning sickness worse in some pregnant women.

Is it Normal to Have a Metallic Taste in the Mouth During Pregnancy?

Yes, it is common to have a metallic taste in the mouth while pregnant. You will find this taste in the first trimester, which subsequently subsides in the later trimesters. Hence, you may not find a metallic taste in your mouth in 3rd trimester of pregnancy as it must have already vanished.

When Do You Experience Metallic Taste in the Mouth During Pregnancy?

Dysgeusia generally manifests during the first trimester of pregnancy and usually fades away as the pregnancy advances or after childbirth. In most cases, the metallic taste sensation improves by the second trimester when the hormones start to settle down a little. Some pregnant women may experience it from time to time throughout their pregnancy, especially after having heartburn or eating something with artificial sweeteners or anything with onions.

There might be other reasons for the metallic taste in your mouth that are not related to pregnancy, such as diabetes, gingivitis, kidney or liver disease, cancer or cancer treatments, or having certain dental appliances or fillings. But if you do not have any of these issues, then the metallic taste is simply because of the fluctuating hormones during pregnancy. However, if you are facing other issues along with the metallic taste, it is wise to consult your doctor.

What Are the Causes of Metallic Taste in the Mouth During Pregnancy?

The real cause of a metallic taste in the mouth during pregnancy is unknown. But here are some of the probable causes:

  • Dysgeusia during pregnancy commonly arises owing to pregnancy hormones. The hormone — oestrogen, in particular, seems to be a controlling factor moderating the sense of taste in pregnant women. Variations in the oestrogen levels during pregnancy can fluctuate the sense of taste, and women may feel a metallic taste in their mouths.

  • The senses of smell and taste are closely linked. So, if something smells unpleasant, chances are it may trigger a foul taste in the mouth as well.

  • Some believe that dysgeusia occurs to ensure that pregnant women consume the necessary amounts of sodium and iron.

  • Change in the gustatory sense during pregnancy.

How Long Does Dysgeusia Last During Pregnancy?

Different women have different experiences during their pregnancy. Some women may have dysgeusia, while others may not. Know how long it lasts:

  • Some pregnant women may not develop dysgeusia or a metallic taste at all, while some may experience it right from the start of their pregnancy.

  • More often than not, the condition of dysgeusia gets better with the progression of pregnancy.

  • The intensity of the metallic taste in the mouth in pregnancy’s second trimester will greatly reduce and completely vanish by the third trimester, just like morning sickness.

  • But in some cases, the metallic taste may linger on throughout the pregnancy.

  • Dysgeusia during pregnancy is not a worrisome condition, provided it doesn’t interfere with eating habits and leads to extreme nausea.

  • It normally doesn’t require any medical treatment.

  • It can be difficult to prevent the incidence of dysgeusia during pregnancy though it may be possible to ease some of the discomfort caused by.
