Hormonal Imbalances: The Root Cause?
Hormones regulate ovulation and menstruation. Even minor hormonal imbalances can disrupt your cycle.

Missed or late periods

Excessive bleeding during periods

Acne, weight gain, and unwanted hair growth
Thyroid Disorders
-
Hypothyroidism (underactive thyroid) can lead to heavy or infrequent periods
-
Hyperthyroidism (overactive thyroid) may result in lighter or more frequent periods
-
Stress & Cortisol: The Silent Cycle Disruptor High stress increases cortisol levels, affecting ovulation and leading to skipped or delayed periods.
