If you’re pregnant and suddenly notice a strange metallic taste in your mouth, don’t panic! This odd pregnancy symptom is often described as tasting like coins or having a “tinny” sensation. It’s called dysgeusia, and it’s a common side effect during the first trimester of pregnancy.
What Causes Dysgeusia During Pregnancy?
The primary culprit behind this metallic taste is the surge of hormones, particularly estrogen. Estrogen plays a big role in your sense of taste and smell, and when its levels fluctuate during pregnancy, it can make certain foods taste different or cause that persistent metallic sensation. Other contributing factors can include:
- Increased blood flow: Pregnancy increases circulation, which can heighten taste and smell sensitivity.
- Morning sickness: Nausea and vomiting can alter your perception of flavors.
- Prenatal vitamins: Some supplements, especially those containing iron, can leave a metallic aftertaste.
- Dehydration or acid reflux: Both conditions can contribute to changes in taste.

How Can You Manage the Metallic Taste?
The good news is that dysgeusia is usually temporary and fades as pregnancy progresses. In the meantime, there are a few simple strategies you can try to reduce the sensation.
- Stay hydrated. Drink plenty of water throughout the day.
- Rinse with saltwater or baking soda. Mix ¼ teaspoon of baking soda or salt in a glass of warm water and rinse your mouth.
- Eat citrus or tart foods. Sucking on lemon slices, chewing sugar-free gum, or eating vinegar-based foods may help neutralize the taste.
- Brush and floss regularly. Good oral hygiene can reduce lingering metallic flavors.
- Try different proteins. If meats taste unpleasant, opt for plant-based proteins like beans, nuts, or tofu.
While this metallic taste can be annoying, it’s typically harmless. However, if it becomes overwhelming, affects your ability to eat, or persists beyond pregnancy, don’t hesitate to reach out to your healthcare provider.
