Type 1 diabetes and life insurance

The realistic expectation

Type 1 is an autoimmune condition, usually diagnosed in childhood or early adulthood, in which the pancreas produces little or no insulin. Insulin is required from diagnosis onward, permanently.

Insurers understand this well. Applications are assessed and offers are made, and the usual outcome is an offer carrying a rating rather than standard rates. The size of that rating varies substantially, and it is one of the areas where the difference between insurers is largest.

Declines happen, and they are more often driven by recent instability or documented complications than by the diagnosis itself.

Duration and onset age

Two related things, weighted differently from the way people expect.

Someone diagnosed at seven and applying at thirty has lived with the condition for over two decades. That duration matters, because the risk of complications accumulates with years of exposure rather than with the diagnosis alone.

The flip side is that a long history is also a long record. Twenty-three years of well-documented management with clean screening results is a substantial piece of evidence, and it is more persuasive than three years of the same.

A recent diagnosis is not automatically favourable. New Type 1 often means treatment still being established, and underwriters generally prefer to see a settled pattern before assessing. A postponement in the first year or two after diagnosis is a common and reasonable outcome.

Hypoglycemia is the factor people underestimate

Applicants tend to arrive worried about their average glucose. Underwriters are frequently more interested in the lows.

Severe hypoglycemia, meaning an episode requiring assistance from another person, is treated seriously. It represents an event that could have been dangerous, and it can happen to someone whose overall numbers look excellent. A history of these episodes, particularly recent or repeated ones, carries real weight.

Impaired awareness of hypoglycemia, where the usual warning symptoms no longer register, is among the factors underwriters treat most cautiously. Someone who no longer feels a low coming has lost the protective mechanism that lets most people act in time.

If neither applies to you, that is worth having documented in your records, because its absence is a genuine positive in the file.

Ketoacidosis

Episodes of diabetic ketoacidosis are recorded and asked about. What matters is how many, how recently, and what the circumstances were.

A single episode at diagnosis, before the condition was known about, sits differently from repeated hospital admissions over recent years. The latter reads as instability, and instability is what underwriters price for.

Complication screening

The screening results usually carry more weight than the glucose numbers themselves, because they show what has actually happened rather than what might.

Underwriters look at kidney function and protein in the urine, at eye examinations for retinopathy, at foot and nerve examination findings, and at any cardiovascular investigation. Where kidney involvement is present, that becomes a significant factor in its own right and interacts with the broader picture described in kidney disease.

Clean screening after many years with the condition is one of the strongest things a Type 1 file can contain.

Technology helps your case

This is genuinely useful and often overlooked.

A continuous glucose monitor or insulin pump produces detailed records: time spent in the target range, the frequency and depth of low readings, and how variable the glucose pattern is. That is a far richer picture than a lab value taken every few months.

Where those records show a stable pattern, having them in your medical file gives an underwriter something concrete to work with. Speak to your diabetes team about what is included in your records, and mention when you apply that the data exists. An underwriter assessing an unclear file assesses it cautiously.

Applying sensibly

Apply for fully underwritten coverage first. The variation between insurers on Type 1 is wide enough that going to a single company and treating its answer as final is genuinely costly.

Have the details ready: age at diagnosis, current insulin regimen and delivery method, the name of your endocrinologist or diabetes clinic, when your last screening appointments were, and an honest account of any severe lows or ketoacidosis episodes.

If the offer comes back rated, compare it against the alternatives properly. A rated fully underwritten policy typically allows far more coverage at a better price than simplified issue, and both are usually better than guaranteed issue. See ratings and substandard offers.

Ratings can often be reviewed later where the record has been stable for a period. Ask at issue whether the insurer will reconsider and after how long.
