Common concerns and tips

Constipation is now common — progesterone slows gut transit. Fibre, dried fruit, water. No laxatives without medical advice.

These recommendations follow DGGG, BZgA, NHS and WHO guidelines. They do not replace individualised medical advice. For gestational diabetes, allergies, or special dietary needs, consult your midwife or OB/GYN.
