A pre-existing health condition doesn't automatically close the door on life insurance. But it does change the conversation — sometimes significantly. Understanding how underwriters think about common conditions helps you approach the process realistically and without unnecessary anxiety.
Insurers categorise pre-existing conditions on a spectrum from "minor loading required" to "declined." The position on that spectrum depends on the severity of the condition, how well it's controlled, its duration, and whether it has led to any complications or hospitalisations.
Conditions that typically result in a premium loading (higher premium) rather than rejection: well-controlled hypertension, well-controlled Type 2 diabetes (HbA1c under 8), treated thyroid conditions (on stable medication), resolved past conditions like appendicitis or minor surgery.
Conditions that may result in partial exclusions (the condition and its direct consequences are excluded from cover, but the rest of the policy is valid): liver conditions, respiratory conditions, certain cardiovascular histories.
Conditions that are more likely to result in deferral or decline: active cancer treatment, recent heart attack or stroke (within 2–3 years), severe uncontrolled diabetes with complications, HIV.
The practical advice: apply with full, honest disclosure. Work with an advisor who knows which insurers are more lenient on specific conditions. Don't assume rejection before you've actually applied.
