Can a health condition stop me from becoming a pilot?
The CAA does not apply blanket rules. Most conditions are assessed individually by an Aeromedical Examiner (AME), and many people hold valid medical certificates while managing ongoing health conditions. The question is usually not whether a condition exists — it's whether it creates a meaningful risk to safe flight.
Individual assessment, not blanket rules
The CAA's approach to medical certification is built around individual assessment rather than automatic exclusion. When you see an AME, they review your specific circumstances: your medical history, your current treatment, how stable your condition is, and how it might interact with the demands of flying.
The central question an AME is asking is whether your condition creates a meaningful risk to safe flight — not simply whether it appears on a list. Many conditions that might sound disqualifying at first are manageable within the Class 2 medical standard required for a PPL.
This means that reading a generic list online and concluding that your situation is hopeless is rarely accurate. The only way to get a reliable answer is to speak to an AME about your specific circumstances.
Common areas of concern
Vision. Corrected vision is permitted. If you wear glasses or contact lenses, that is not an obstacle — provided your corrected acuity meets the required standard. Colour vision deficiency is assessed individually: some deficiencies are accepted for Class 2 with no restriction, while others may result in a limitation but still permit certification.
Hearing. Mild hearing loss is often acceptable. The assessment looks at whether communication in a cockpit environment is practical — it is not simply a measure of absolute hearing thresholds.
Cardiovascular. Well-controlled hypertension is usually manageable within the standard. A history of cardiac events is assessed individually — it does not automatically exclude you, but it does require review. The outcome depends on the nature of the event, how long ago it occurred, and your current condition.
Neurological. Epilepsy and a history of unprovoked blackouts are among the more significant concerns. A seizure-free period and specialist review are typically required. A single event in the distant past with a clear, identified cause is treated differently from an ongoing or recurring condition — the AME will consider the full picture.
Mental health. Anxiety and depression are common conditions and do not automatically prevent certification. The CAA and AMEs assess stability, the nature of the condition, and current treatment. Many pilots hold valid medicals while managing these conditions. Openness with your AME is important — disclosure is always better than omission.
Diabetes. Insulin-treated diabetes was historically excluded from Class 2. The CAA now has pathways for insulin-treated applicants through the OHMP (Operational Health Management Plan) process. This involves specialist review and ongoing monitoring, but certification is possible for suitable applicants.
Speak to an AME first
Before booking a formal medical assessment, most AMEs are happy to have an informal conversation about your specific situation. This costs nothing and gives you a realistic picture of your prospects before you commit to an assessment fee.
The CAA publishes a list of approved AMEs on its website. Many have experience with a wide range of conditions and can give you a straightforward view of where you stand. In many cases, the answer is more positive than people expect after reading generic information online.
The key point is not to self-exclude before speaking to someone qualified to assess you. An informal call with an AME is a low-cost way to get reliable information.

Complex applications
Where a condition requires specialist review beyond what an AME can assess at the initial appointment, your application may be referred to the CAA's Aircrew Medical Section. This is a normal part of the process for more complex cases — it is not a refusal.
Some conditions are handled through the OHMP process, which involves specialist sign-off and an ongoing monitoring plan. An experienced AME will advise you on the right route for your circumstances and can help you understand what supporting documentation is likely to be required.
Complex applications take longer, but they are often resolved positively. If you know your situation is likely to involve specialist review, building that time into your planning is worthwhile.
