Body mass index and fertility are closely linked. Being underweight or overweight can affect hormones, ovulation in women, and lower sperm quality in men—reducing the chances of conception. In the UAE, where 44.2% of women and 30.9% of men are obese, the impact of weight and fertility is a growing concern (Source: *Global Nutrition Report ). Maintaining a healthy BMI is key to improving reproductive health.

What is BMI and Why Does It Matter?

Body Mass Index (BMI) is calculated by dividing the weight in kilograms by height in meters squared (kg/m²). The BMI categories are underweight (below 18.5), normal (18.5-24.9), overweight (25-29.9), and obese (30 and above). BMI acts as a useful screening tool for overall health. It is important to assess metabolic and reproductive health, as both underweight and overweight levels can impact fertility and hormonal balance.

Dr Batra’s® pro tip:

"Maintaining a balanced BMI is not just about weight—it’s about your overall health. A nutritious diet and regular exercise can naturally boost fertility and hormonal balance. Homeopathy supports this journey by correcting internal imbalances, improving metabolism, and promoting healthy ovulation. So, do not wait for problems to arise—start making healthy choices today for better reproductive health tomorrow.."

Effects of Being Overweight on Female Fertility

Excess weight can interfere with a reproductive system of women in many ways from hormonal imbalances to reduced treatment success. Maintaining a healthy BMI is the key to improving fertility outcomes.

  • Hormonal Imbalance: Increased body fat raises estrogen levels, disrupting ovulation.
  • Irregular Menstrual Cycles: Makes it more challenging to track or achieve conception.
  • Higher Risk of PCOS: Common in overweight women, leading to ovulatory issues.
  • Insulin Resistance: Affects egg quality and ovulation.
  • Chronic Inflammation: Negatively impacts ovarian function and hormone levels.
  • Lower IVF Success Rates: Extra weight may reduce the effectiveness of fertility treatments.
  • Better Outcomes with Weight Loss: Even modest weight loss can restore cycle regularity and improve fertility.

Effects of Being Underweight on Female Fertility

Low body weight can disrupt key productive functions and reduce the chances of conception.

  • Estrogen Deficiency:Low body fat leads to insufficient estrogen, which can affect fertility
  • Irregular or Missed Periods: Amenorrhea is common. This makes ovulation unpredictable.
  • Higher Miscarriage Risk:Poor hormonal support increases loss of pregnancy.
