What is BMI?BMI or Body Mass Index is a widely used measurement to calculate whether your weight is appropriate for your height. BMI does not measure body fat, but it does provide a general estimate of whether you are underweight, overweight or at a normal weight. BMI is a quick screening tool for potential health risks, like cardiovascular issues, diabetes or fertility issues. Maintaining a healthy BMI can help with balancing hormones, ovulation and an overall smoother pregnancy journey. However, it is important to remember that BMI is not perfect. It does not account for muscle mass, fat distribution or bone density. It should be used alongside other health assessments. Consult your doctor for a complete picture of your overall health and well-being.How BMI is Related to PregnancyBody Mass Index or BMI has a crucial role to play in conception and pregnancy. It supports hormonal balance and regulates ovulation, both of which are essential for conception. Being underweight with a BMI lower than 18.5 can lead to irregular periods or missed ovulation while being overweight with a BMI over 25 might be linked to conditions such as PCOS, insulin resistance or irregular cycles, all of which affect fertility.BMI continues to play an important role in pregnancy. Women with a higher BMI may face increased risks of complications such as gestational diabetes, high blood pressure, preeclampsia, or challenges during labour and delivery. Underweight women may have a higher chance of delivering prematurely or having a baby with low birth weight.Maintaining a healthy BMI before and during pregnancy can improve your chances of conceiving naturally, support a smoother pregnancy, and promote better outcomes for both mother and baby. While BMI is not the only factor to consider, it's a valuable starting point for understanding your preconception health.Always consult your doctor for more information and personalised guidelines.

How BMI Is CalculatedBMI is calculated by dividing a person's weight in kilograms by the square of their height in meters (kg/m²). For most adults, a BMI between 18.5 and 24.9 is considered healthy.Range Wise TipsIf your BMI is under 18.5 and you are trying to conceive:

Focus on gaining weight through nutrient-rich foods like whole grains, healthy fats, lean proteins, and dairy.
Track your menstrual cycle since if you are underweight, you may have irregular or absent periods.
Include strength-building exercises to support healthy weight gain and hormonal balance.
Consult a doctor or nutritionist to rule out underlying conditions and create a safe weight gain plan.

If you are within the normal range and trying to conceive (18.5-24.9)

Maintain your current lifestyle with balanced nutrition and regular physical activity.
Start prenatal vitamins, especially folic acid, to prepare your body for pregnancy.

Monitor your cycle and track ovulation to optimise timing.
Continue regular check-ups to keep all health markers in range.

If your BMI is over 25 and you are trying to conceive:

Aim for gradual weight loss through moderate exercise and a clean, portion-controlled diet.
Losing just 5–10% of your body weight can improve ovulation and fertility.
Limit sugar, refined carbs, and processed foods; increase fibre and plant-based meals.
Get checked for PCOS or insulin resistance.
