Life insurance if you take Mounjaro or Wegovy

16 September 2026

A weight loss injection does not stop you getting life insurance. Insurers want to know why it was prescribed, and what your weight was before it.

The short answer

Yes, you can still get cover, and yes, you must declare the medication. Insurers underwrite the reason it was prescribed rather than the drug. Prescribed for type 2 diabetes, it is assessed as diabetes. Prescribed for weight management, your body mass index and related conditions drive the terms.

Do you have to declare Mounjaro or Wegovy?

Yes. A GLP-1 injection such as tirzepatide or semaglutide is a prescribed medication, and applications ask about prescribed medication.

It does not matter whether it came from your GP, a specialist weight management service or a regulated online pharmacy.

The prescriber and pharmacy keep a record either way, and non-disclosure is one of the most common reasons a claim fails.

Brand names people recognise include Mounjaro and Wegovy. NICE has published guidance on both tirzepatide and semaglutide for managing overweight and obesity.

The underwriting question is not the drug.

It is what the drug was prescribed for. A GLP-1 prescribed for type 2 diabetes is underwritten as diabetes. One prescribed for weight management is underwritten as a weight history.

Why the reason you take it matters

There are two common routes to a GLP-1 prescription, and they lead to different applications.

Prescribed for type 2 diabetes

The underwriting follows the diabetes, not the injection. Your HbA1c, time since diagnosis and any complications drive the terms.

The medication itself is generally viewed as evidence of active management rather than as a negative.

Prescribed for weight management

Here the insurer is underwriting your weight history and the reasons behind it.

Expect questions about your height and weight now, your weight before treatment, and any related conditions such as high blood pressure, raised cholesterol, sleep apnoea or joint problems.

Body mass index is a standard underwriting factor and always has been. The injection did not introduce it.

Some insurers will want to see that weight has been stable rather than mid-change, because a moving figure is hard to price.

Life insurance terms on weight loss injections

There is no standard market answer yet, and stances are still moving as insurers gather data.

What is consistent is that a high body mass index has always attracted a rating, and that ratings reduce as weight comes down and stays down.

Life insurance. Usually available. A rating is likely if body mass index is still high, and it reflects the weight rather than the medication.
Critical illness cover. Similar, with more attention to related conditions such as blood pressure and diabetes.
Income protection. More sensitive to musculoskeletal and mobility issues linked to weight.
Timing. Some insurers prefer a period of stable weight before offering the best terms.

Do not stop a prescribed treatment to improve an application. That is a medical decision, not an insurance one, and stopping can make the health picture worse.

Equally, do not delay cover indefinitely waiting for a perfect number. Cover in force today beats a better price you never get round to buying.

Practical steps before you apply

Write down your current height and weight, your weight before treatment, the drug, the dose and the start date.
Note why it was prescribed, and by whom, because a specialist referral tells a clearer story than a bare prescription.
List related conditions honestly, since blood pressure and cholesterol are usually what move the price.
Ask for pre-assessment across several insurers, because stances on GLP-1 medication vary right now.
If you already hold cover, keep it. A new application does not affect an existing policy.
Diarise a review once your weight has been stable for a year, because ratings can be reduced.

The review point is the one that pays. Someone rated at a high body mass index who then sustains a lower weight is often a materially better risk.

That improvement does not reach your premium unless you go back and ask.

Frequently asked questions

Do I have to tell my insurer I am taking Mounjaro or Wegovy?

Yes, if the application asks about prescribed medication, which almost all do. It applies whether the prescription came from your GP or a regulated online pharmacy.

Will a weight loss injection make life insurance more expensive?

Not by itself. Insurers price the underlying reason, which is usually body mass index or type 2 diabetes. A high body mass index has always attracted a rating, and the medication does not create that.

Is a GLP-1 prescribed for diabetes treated differently?

Yes. If it was prescribed for type 2 diabetes, the application is underwritten as diabetes, using your HbA1c, time since diagnosis and any complications.

Should I wait until I have lost weight before applying?

Usually not. Cover in force protects you now, and most ratings can be reviewed later once weight has been stable. Waiting leaves you uninsured in the meantime.

Can I get my premium reduced after losing weight?

Often yes, but you have to ask. Insurers do not review ratings automatically. Once your weight has been stable for a period, it is worth retesting the market while keeping the existing policy in force.

Does buying the medication privately keep it off my record?

No. A regulated pharmacy still records the prescription, and the duty to declare it is the same. Declaring it is far cheaper than a disputed claim.
