Malnutrition's Impact on Puberty and Reproductive Development
Malnutrition profoundly affects puberty and reproductive health:
- Delayed puberty onset: Nutrient deficits (protein, vitamins, minerals) impair hormone production (GnRH, LH, FSH, sex steroids).
- Stunted growth: Reduced height, bone density, body proportions.
- Hormonal disruption: Alters estrogen, progesterone, testosterone, growth hormone.
- Impaired sexual development: Delayed breast/testicular development.
- Menstrual irregularities/amenorrhea: Indicates inadequate energy for reproduction.
- Reduced fertility: Affects sperm quality, ovulation.
- Pregnancy complications: Low birth weight, developmental issues in offspring.
Severity, timing, and specific nutrient deficiencies influence outcomes. Adequate nutrition during adolescence is critical for lifelong reproductive health.
