Condition cannot be rectified. Candidate is ineligible for that wing regardless of treatment. Examples: keratoconus, epilepsy, ACL reconstruction, cardiac surgery.
Condition is rectifiable. Candidate may reappear after treatment within the prescribed recovery period. Examples: DNS, varicocele, overweight, hydrocele.
The SMB → AMB → RMB Appeal Ladder
After receiving an SSB recommendation, candidates undergo a medical examination. There are three boards in the process:
SMB — Special Medical Board
Conducted at a designated Armed Forces hospital after SSB recommendation. This is your first formal medical examination. Result: Fit or Unfit. If declared Fit, you proceed to merit listing. If declared Unfit, you may appeal via AMB.
AMB — Appeal Medical Board
Available to candidates declared Unfit at SMB. You must request it within the timeline communicated by the President SMB. Held at a Command Hospital, typically within approximately 42 days of the SMB date. Board proceedings are confidential; only the Fit/Unfit outcome is communicated to you.
RMB — Review Medical Board
Available after an AMB Unfit verdict. Must be requested within ONE day of the AMB result. RMB is NOT a matter of right — it is granted at the sole discretion of DGAFMS on merit. Venues: Delhi or Pune only. No further board exists after RMB.

Rectifiable (Temporary) Rejection Reasons
The NDA Notification Appendix IV para 2 lists defects that candidates should rectify before appearing at the medical board. These conditions may result in a Temporarily Unfit verdict if found during SMB.
| Defect | How to Rectify | Min Recovery Before SMB |
|---|---|---|
| Wax in ears | ENT cleaning (syringing or suction) | Immediate |
| Deviated Nasal Septum (obstructing) | Surgical correction (septoplasty) | 4–6 weeks post-op |
| Hydrocele | Surgical correction (hydrocoelectomy) | 8 weeks post-op |
| Phimosis | Surgical correction (circumcision or preputioplasty) | 4 weeks post-op |
| Overweight / Underweight | Diet + exercise to bring weight within chart range | Before medical date |
| Under-sized chest | Physical conditioning (compound exercises, swimming) | Before medical date |
| Piles (haemorrhoids Grade III/IV) | Surgical treatment (haemorrhoidectomy) | 12 weeks post-op |
| Gynaecomastia | Surgical correction (subcutaneous mastectomy) | 12 weeks post-op |
| Tonsillitis | Tonsillectomy if indicated; benign histology required | 2 weeks post-op |
| Varicocele | Surgical correction (varicocoelectomy or embolisation) | 8 weeks post-op |
Other Commonly Treatable Conditions
These conditions do not appear on the official "rectify before SMB" list but are frequently encountered and can affect your medical outcome. Address them well in advance:
- Dental caries / calculus: Scale and fill all teeth before the medical. Examiners count dental points; significant untreated decay can affect fitness grading.
- Mild pyorrhoea: Periodontal treatment including scaling, root planing, and gingival therapy.
- Warts / corns: Treat at least 3 months before the medical board date.
- Mild acne: Dermatological treatment; severe cystic acne may be independently evaluated.
- Fungal infections: Topical antifungal; infection must be completely cleared before examination.
- Mild iron-deficiency anaemia: Iron supplementation for 4–6 weeks; confirm Hb levels are within normal range before the medical.
What Does "Temporarily Unfit" Mean?
At the SMB, some candidates receive a verdict of "Temporarily Unfit" rather than simply "Unfit." There is an important distinction:
| Verdict | Meaning | Next Step |
|---|---|---|
| Temporarily Unfit | A treatable condition is present. The board specifies a recovery period after which you may be re-examined. | Get treated; reappear at SMB after the specified period |
| Unfit | A condition that may be permanent or serious has been found. The candidate may appeal via AMB. | Request AMB within the specified window |
| Fit | Candidate meets all medical standards for the applied wing. | Proceed to merit list |
The "Temporarily Unfit" route is separate from the AMB/RMB appeal route. If you are Temporarily Unfit, you do not go through AMB — you simply get treated and present for re-examination.
Borderline Cases — When to Appeal
If you are declared Unfit at SMB for a condition you believe was incorrectly assessed or borderline, the AMB is your right and you should request it:
- Documentation to bring: Operative notes, post-op discharge summaries, specialist clearance letters, investigation reports, imaging studies (X-rays, MRIs, ECGs).
- White-coat hypertension: If borderline BP at SMB, a 24-hour ABPM (ambulatory blood pressure monitoring) report from a cardiologist confirming normal ambulatory readings can support your AMB case.
- Borderline hearing loss: Unilateral mild loss near the threshold — a formal audiological assessment with PTA and speech discrimination scores from a tertiary ENT centre strengthens your case.
- Mild flat feet: If you were tested under suboptimal conditions, a formal podiatric assessment and functional performance evidence may help at AMB.
Frequently Asked Questions
What are the most common reasons for NDA medical rejection?
The most common NDA medical rejection reasons include vision defects (keratoconus, manifest squint, poor distant vision uncorrected), musculoskeletal issues (ACL reconstruction, flat feet beyond limits, knock knees), ENT problems (DNS, tympanoplasty), overweight or underweight, dental issues, and varicocele. Some are permanent disqualifiers; others are rectifiable before the SMB.
What conditions lead to permanent rejection from NDA?
Conditions that permanently disqualify a candidate from NDA include: keratoconus, epilepsy, any cardiac surgery or congenital cardiac anomaly, ACL reconstruction (regardless of time elapsed), history of mental illness or psychosis, drug dependence, sickle cell disease, beta thalassaemia (including trait), haemophilia, active varicose veins, club foot, and extensive vitiligo on exposed parts, among others.
What is temporary rejection in NDA medical?
Temporary rejection (or "Temporarily Unfit") means the candidate has a condition that is present but can be treated or rectified. The candidate is given a recovery period and may reappear at the medical board after treatment. Examples include deviated nasal septum, hydrocele, varicocele, overweight/underweight, and phimosis.
Can I appeal after being rejected at the NDA SMB?
Yes. Candidates declared Unfit at the SMB (Special Medical Board) can request an AMB (Appeal Medical Board) within the timeline communicated by the President SMB. If still found Unfit at AMB, they can request an RMB (Review Medical Board) within ONE day — but RMB is not a right and is granted at the discretion of DGAFMS on merit.
What is the difference between SMB, AMB and RMB?
SMB (Special Medical Board) is the first examination after SSB recommendation at a designated Armed Forces hospital. AMB (Appeal Medical Board) is available to candidates declared Unfit at SMB, held at a Command Hospital within approximately 42 days. RMB (Review Medical Board) is a discretionary final review available after AMB unfit verdict, held only at Delhi or Pune.
Is knock knees a reason for NDA rejection?
Yes, knock knees (genu valgum) beyond the prescribed limits can be a reason for NDA medical rejection. Mild knock knees may be acceptable depending on the degree of deformity, but significant knock knees causing functional impairment are disqualifying.
Can I join NDA after getting a defect treated?
For temporary/rectifiable conditions (such as DNS, hydrocele, varicocele, overweight), yes — after successful treatment and adequate recovery, you may reappear at the medical board. However, for permanently disqualifying conditions (such as ACL reconstruction, keratoconus, epilepsy), no amount of treatment will make you medically eligible.
How long does the NDA appeal medical board process take?
The AMB (Appeal Medical Board) is typically held within approximately 42 days of the SMB result. The RMB (Review Medical Board), if granted, is held at Delhi or Pune and the timeline varies. Board proceedings are confidential; only the Fit/Unfit outcome is communicated to the candidate.
