Everything tastes metallic, bitter, or simply wrong. You cannot eat your favourite foods. Even water tastes strange. Dysgeusia - an altered or phantom taste - affects up to 93% of pregnant women in some studies, making it one of the most common and least-discussed early pregnancy symptoms.
What Causes It
The primary cause is rapidly rising estrogen levels, which directly affect taste bud sensitivity and saliva composition. HCG (the pregnancy hormone) also plays a role. The effect typically peaks in the first trimester alongside morning sickness and often improves or disappears by the second trimester.
| Cause | Effect |
|---|---|
| Rising estrogen | Alters taste bud function and saliva pH |
| HCG hormones | Amplifies smell and taste sensitivity |
| Increased salivation | Changes the chemical environment of the mouth |
| Prenatal vitamins (especially iron) | Can contribute to metallic taste |
What Helps
- Eat cold foods - cold temperatures reduce the intensity of the metallic taste compared to hot food
- Use plastic cutlery instead of metal - this sounds minor but makes a noticeable difference for many women
- Rinse your mouth with a baking soda solution (half teaspoon in water) before meals to neutralise taste receptors
- Citrus foods and drinks - sour flavours override metallic ones
- Brush your tongue as well as your teeth - this reduces the metallic coating sensation
- Switch prenatal vitamin brands - ask your doctor if a different iron formulation helps
- Cold sparkling water helps many women more than still water
When it ends
Dysgeusia almost always improves significantly or disappears by the second trimester as estrogen levels stabilise. If it persists strongly past 20 weeks, mention it to your doctor to rule out other causes.
