Life cover for people on weight loss medication: What You Need to Know

If you have a high BMI (Body Mass Index), you might be wondering how it affects your chances of getting life insurance. The good news is that obtaining life insurance, critical illness cover and income protection is still possible, even if you’re classified as overweight or obese. However, your BMI may influence the price you pay and the cover options available to you.

You can use the free NHS BMI calculator tool to determine your BMI*

Weight loss medications like Ozempic and Mounjaro are changing the landscape of obesity treatment in the UK—and they’re also reshaping how insurers view your lifestyle. Being transparent and proactive can help you secure affordable life insurance, even if you’re managing your weight with medication.

What Is BMI and Why Does It Matter for Insurance purposes?

BMI is a measurement used to determine whether your weight is healthy for your height. It’s calculated by dividing your weight in kilograms by your height in metres squared.

  • 18.5–24.9 = Healthy
  • 25–29.9 = Overweight
  • 30–39.9 = Obese
  • 40+ = Severely obese

Life insurers use BMI as part of their risk assessment during underwriting. A high BMI may be linked to increased health risks, such as heart disease, diabetes, or high blood pressure — all of which insurers factor in when determining your premium.

Do Weight Loss Drugs Affect Life Insurance?

Yes, they can. Life insurance providers assess risk based on health status, medical history, and lifestyle factors. When applying for life insurance, you’re typically required to disclose:

  • Current medications (including weight loss drugs)
  • Diagnosed health conditions (e.g., obesity, diabetes, hypertension)
  • Recent weight changes
  • Smoking status and alcohol consumption

Taking weight loss medication doesn’t automatically raise your premiums, but it does signal to insurers that you’re managing a health condition—usually obesity or diabetes—which could impact your risk rating.

How Insurers View Weight Loss Medication
Most UK life insurers don’t penalise you simply for taking a weight loss drug. Instead, they focus on the underlying condition being treated, and how well it is managed.

Key factors life insurers consider:

Presence of related conditions, like Type 2 diabetes, high blood pressure, or heart disease

BMI (Body Mass Index) before and after treatment

Duration of weight loss medication use

Any side effects or complications

What to Disclose in Your Life Insurance Application

Honesty is essential when applying for life insurance. You’ll need to disclose:

  • Any prescribed weight loss medications
  • The condition being treated (e.g., obesity, diabetes)
  • Relevant health data (BMI, blood pressure, cholesterol)
  • Lifestyle changes you’ve made (diet, exercise, smoking cessation)

Please note: Non-disclosure can result in claims being denied or cancellation of your policy.

Can Losing Weight Lower Your Premiums?

Yes—significant and sustained weight loss often leads to better premiums, especially if it results in fewer associated health risks. Some insurers may even review your premiums after 12 months if you’ve made major health improvements.
