What is the link between fasting and hormone balance?

Fasting can influence insulin, cortisol, thyroid hormones, and reproductive hormones. In this episode, we explain how different fasting patterns affect endocrine function and how hormone balance is assessed in Europe.

In this episode, we cover:

• How fasting affects insulin sensitivity and glucose regulation

• Cortisol changes during caloric restriction

• Potential effects on thyroid hormones (T3, T4)

• Impact on menstrual cycles and reproductive hormones

• Testosterone changes in men during prolonged restriction

• Differences between intermittent fasting and extended fasting

• Risks for people with diabetes or eating disorders

• When blood tests may be clinically indicated

• Situations where dietary plans may not be advised

Doctors assess BMI, HbA1c, thyroid function, menstrual history, medication use, cardiovascular risk, and metabolic profile before recommending fasting. Hormonal responses vary between individuals. Persistent fatigue, dizziness, menstrual disruption, or hypoglycaemia require medical evaluation.

This episode reflects how nutrition and endocrine health are reviewed within structured medical assessment in European telemedicine at Mobi Doctor.
