Type-II Diabetes Mellitus Disability Pension in Armed Forces 2026: NANA, Lifestyle Disease, Medical Board Reasons & AFT Remedy

For the general framework, see our Armed Forces disability pension guide. For a focused explanation of medical-board NANA findings, see Attributable or Aggravated by Military Service: NANA and AFT Challenge.

1. Can Type-II Diabetes Mellitus qualify for disability pension?

Yes, depending on the governing rules, medical record and facts. The decisive issue is not simply whether Diabetes Mellitus Type-II exists. The legal question is whether the disability is accepted as attributable to or aggravated by military service, whether the disability percentage satisfies the applicable pension framework, and whether the medical and pension authorities have given legally sustainable reasons for any denial.

In older-rule cases, especially those governed by the 2008 Entitlement Rules and the corresponding Guide to Medical Officers, courts have increasingly rejected formulaic opinions which merely state that diabetes is a lifestyle disorder, a metabolic condition or a disease arising in a peace station. A valid medical conclusion must engage with the individual’s entry medical condition, duration of service before onset, postings, duties, stress and strain, clinical history and any actual alternative causative factors relied upon.

2. Why are diabetes disability-pension claims frequently rejected?

Medical boards commonly record Diabetes Mellitus Type-II as Neither Attributable to Nor Aggravated by military service. Typical expressions include “lifestyle disorder”, “metabolic disorder”, “strong genetic preponderance”, “onset in peace station”, “no close-time association with field service”, or “not connected with military service”. None of these phrases should be read in isolation. Their legal sufficiency depends on whether the applicable rules permit the conclusion and whether the board explains the factual basis for it.

3. Delhi High Court, 3 February 2026: Ex Sgt Ajay Khurana

One of the strongest 2026 authorities is Union of India and Ors. v. Ex Sgt Ajay Khurana, decided by the Delhi High Court on 3 February 2026. The respondent’s Diabetes Mellitus Type-II had been assessed at 20% for life. The AFT granted disability element at 20%, rounded off to 50% for life, from retirement.

The Release Medical Board had treated the disease as NANA because onset was at Thanjavur, a peace station, and because the condition was described as a lifestyle disease. The High Court rejected the Union’s challenge. It noted that the disease arose after approximately 23 years of service and that the RMB did not identify any real alternative cause. The Court also accepted that the respondent’s duties as an Air Field Safety Operator involved unscheduled and demanding work, night duties and disruption of diet and circadian rhythm.

The Court reiterated that under the 2008 Entitlement Rules, if the administration concludes that a disease arising during service is NANA, it must give cogent reasons and identify the cause other than military service. A bare entry such as “onset in peace station” or “lifestyle disorder” was held insufficient in that line of cases.

4. Delhi High Court, 9 January 2026: Ex MWO Suhendra Pal Chauhan

In Union of India & Ors. v. Ex MWO Suhendra Pal Chauhan, decided on 9 January 2026, the Delhi High Court again upheld AFT relief for Diabetes Mellitus Type-II assessed at 20% for life. The respondent had rendered about 38 years of Air Force service and the onset was recorded after many years of service.

The Court noted that the RMB had not identified any independent cause for the diabetes. It agreed with the AFT that cumulative stress and strain of military service, hostile environments, difficult weather and disciplined service conditions could not simply be ignored. The disability element at 20% was rounded off to 50% for life under the applicable broad-banding law.

5. Delhi High Court, 23 January 2026: Ex MWO Asis Pramanik

Another significant 2026 decision is Union of India & Ors. v. Ex MWO Asis Pramanik, where the AFT had granted disability element for Diabetes Mellitus Type-II at 20% for life, rounded off to 50% for life from discharge. The Delhi High Court examined the case within the 2008 Entitlement Rules framework and reaffirmed that where no disease is noted at entry, the administration bears the burden of establishing why the later disability should be treated as non-service connected.

The judgment reinforces an important distinction: a court does not grant disability pension because diabetes exists; it examines whether the military establishment has legally justified denial of service connection under the governing entitlement rules.

6. Kerala High Court, July 2026: Mohanraj TK

The Kerala High Court’s 2026 decision in Union of India v. Mohanraj TK is particularly useful because it dealt with both Type-II Diabetes Mellitus and Primary Hypertension. The Court refused to accept a bare “lifestyle disease” label as sufficient to defeat disability-pension relief and upheld the AFT’s order in favour of the veteran, subject to composite disability assessment.

That judgment is analysed separately in our Mohanraj TK case note on diabetes, hypertension and disability pension. Keeping the case note separate from this guide avoids duplication: the case note explains the judgment; this page explains the broader legal test for diabetes claims.

7. Does peace-station onset automatically defeat a diabetes claim?

No, not in the older-rule cases discussed above. A peace station is a geographical label, not a medical diagnosis. Military personnel in peace areas may still perform operational, technical, command, flying-support, air-traffic, logistics, security, night-shift or emergency duties involving substantial stress and disrupted routines.

However, this does not mean that every peace-station diabetes claim automatically succeeds. The claimant’s duty profile and medical chronology still matter. The legal objection is to mechanical reasoning—not to a genuinely supported medical conclusion.

8. What role does stress and strain play in Type-II Diabetes Mellitus cases?

Stress and strain is often relevant because the older Guide to Medical Officers recognised that stress can precipitate or destabilise diabetes in appropriate circumstances. In litigation, it is therefore useful to move beyond generic assertions such as “military service is stressful” and prove the actual stressors reflected by the record.

9. Entry medical fitness and onset during service

In older entitlement-rule litigation, the fact that no diabetes was recorded at enrolment or commissioning is often important. Recent judgments have required the military establishment to explain why a disease emerging after lengthy fit service should nevertheless be treated as wholly unrelated to service.

This argument should be made carefully. The absence of a disease at entry is a relevant legal and factual point, but the precise presumption and burden depend on the rule set applicable to the claim. It is therefore unsafe to copy an older Dharamvir Singh-style formulation into every post-2023 case without first determining whether the 2023 rules govern.

10. ER 2008 versus ER 2023: why the date matters

The Ministry of Defence stated that death and disability reported or recorded after 21 September 2023 are governed by the 2023 entitlement framework. A current claim must therefore begin by identifying the governing date before relying on older presumptions.

11. What makes a diabetes NANA opinion vulnerable?

A NANA finding may require closer scrutiny where the record shows one or more of the following:

1. No diabetes or glycaemic abnormality was recorded at entry.
2. The person served for a substantial period in fit medical category before onset.
3. The RMB merely writes “lifestyle disease” without identifying personal lifestyle factors.
4. The RMB records “peace station” but does not analyse the actual duties performed.
5. The board does not address documented operational or service stress.
6. The board gives no reason why the condition could not have been caused or aggravated by service.
7. The appellate authority simply repeats the RMB conclusion.
8. The disability percentage is accepted but service connection is rejected through a formulaic sentence.
9. Earlier medical material points to aggravation, while the final board gives no explanation for departing from it.
10. The claimant’s specialist and service records are not discussed.

12. What may support the administration’s NANA conclusion?

A balanced analysis is important. Not every diabetes case is necessarily service connected. A NANA opinion may be more defensible where the medical record identifies and reasons through specific non-service factors, supported by individual evidence, and explains why military service did not materially cause or aggravate the disease under the governing rules.

Examples could include a well-documented pre-existing condition, a specific proven non-service causative factor, a reasoned medical history demonstrating no material service nexus, or an applicable rule that expressly excludes the particular circumstances. The key point is that the conclusion should arise from evidence and the applicable entitlement framework, not from a stock label.

13. Diabetes percentage and broad-banding

Many older diabetes cases involve an assessment of 20% for life. Where entitlement to disability element is established under the applicable legal framework, broad-banding or rounding-off may become relevant. In a number of the recent Delhi cases, 20% was rounded to 50% for life under the settled broad-banding jurisprudence.

Broad-banding is a computation issue. It does not itself establish that the disease is attributable or aggravated. The sequence is therefore:

For arrears and broad-banding after the Supreme Court’s 2026 decision, see Sgt Girish Kumar: disability pension arrears and broad-banding.

14. Diabetes with hypertension or another disability

Where Diabetes Mellitus Type-II co-exists with Primary Hypertension, coronary artery disease, hearing loss, musculoskeletal disability or another accepted disability, the medical board may assess a composite degree of disablement. Composite assessment should not be confused with simple arithmetic addition. The board must apply the governing medical methodology.

If individual disabilities are accepted at different percentages but the composite figure or qualifying percentage is disputed, the claim may involve both entitlement and assessment issues. The hypertension-specific legal position is discussed in our Primary Hypertension disability pension guide.

15. Departmental First Appeal and Second Appeal

Where disability entitlement is rejected, the departmental appellate mechanism should be used carefully. A strong appeal should not simply state that the claimant served the country or that the disease arose in service. It should identify the precise error in the medical reasoning.

A focused diabetes appeal can address:

• entry medical fitness;
• date and circumstances of onset;
• years of service before onset;
• specific duty profile and stressors;
• field, operational and peace postings;
• sleep and shift pattern where relevant;
• absence of identified alternative causative factor;
• failure to apply the governing entitlement rule correctly;
• failure to address relevant Supreme Court or High Court authority for an older-rule case.

16. When can the Armed Forces Tribunal be approached?

Once the departmental cause is ripe, the Armed Forces Tribunal can examine whether the denial of disability-related pensionary entitlement is sustainable. The Tribunal may consider the medical board, adjudication, appellate orders, service profile, medical record and applicable entitlement framework.

The AFT does not simply substitute its own medical opinion for that of specialists. The challenge is stronger where the board’s conclusion is unsupported, internally inconsistent, contrary to the governing rules, based on irrelevant considerations, or expressed without reasons.

19. Reassessment is different from entitlement

If the dispute is that diabetes has worsened after retirement, that may involve reassessment or resurvey rather than the original question whether the disease is service connected. These issues should not be mixed. See our disability pension reassessment and resurvey guide.

20. Frequently asked questions

Is Type-II Diabetes automatically a lifestyle disease for pension purposes?

No. A medical board may consider lifestyle factors, but a legal denial should rest on the governing rules and a reasoned individual assessment rather than a stock label.

Can diabetes arising at a peace station qualify?

In older-rule cases, yes, depending on facts. Recent Delhi High Court decisions have rejected peace-station onset as a complete answer where the board failed to examine the actual duties and failed to identify another cause.

What if diabetes was diagnosed after 20 or 30 years of service?

Long fit service before onset is an important factual circumstance, but not an automatic guarantee. It strengthens the need for a reasoned explanation if the authorities treat the disease as wholly non-service connected.

Can 20% diabetes disability be rounded to 50%?

Where disability element is otherwise payable and the applicable broad-banding framework applies, courts have repeatedly granted rounding of 20% to 50% in covered cases.

Does ER 2023 change the analysis?

Yes. Disabilities reported or recorded after 21 September 2023 must be examined under the 2023 entitlement framework and GMO 2023. Older judgments should not be applied mechanically without first determining the governing rules.

Can an AFT challenge succeed against a medical board?

Yes, where the medical opinion is legally defective, unreasoned, inconsistent with the record or based on an incorrect rule. The Tribunal does not simply replace medical expertise; it reviews the legality and rationality of the decision.

21. Key takeaway

The strongest Type-II Diabetes disability-pension case is not built around the proposition that every diabetic veteran must receive disability pension. It is built around the proposition that entitlement must be decided under the correct rule set, on the actual service and medical record, and through a reasoned medical opinion. A finding of “NANA” must therefore withstand scrutiny on both medicine and law.

For older-rule claims, the 2025–2026 Delhi High Court line has materially strengthened challenges to bare “lifestyle disorder” and “peace station” reasoning. For current cases governed by ER 2023, the argument must be re-framed around the newer entitlement criteria rather than merely repeating older presumptions.
