A peanut allergy will now disqualify you from joining the U.S. Military. So will diabetes, sickle cell disease, an active cancer, a pacemaker, or 23 other medical conditions on a new prescreening list that took effect May 4. The U.S. Military Entrance Processing Command rolled out the change to spare applicants “false hope” before they reach the physical exam stage.
The U.S. Military Has Some New Things That Could Get You Disqualified from Joining

According to recent news reports, the U.S. Armed Forces is changing how it prescreens potential recruits.
The new standard set forth by the U.S. Military Entrance Processing Command (MEPCOM) now includes 28 medical conditions that are considered disqualifying for service.
The new prescreening process is intended to preemptively disqualify candidates from the armed services who would likely have been discharged later for health issues. The new prequalification standards are part of a broader effort to increase the overall health and readiness of the U.S. Military.
Implementing New U.S. Health Standards
MEPCOM announced new changes on Monday, May 4, stating that the U.S. Armed Services were implementing a new prescreening process that disqualifies applicants much earlier in the process.
Applicants who have one of the 28 medical conditions listed in the new guidelines will no longer be required to undergo a physical exam with a doctor to join the military. “It is a process change that stops processing for applicants with one or more specific disqualifying conditions that have been identified by service waiver authorities as unlikely to be waived,” Marshall Smith, a spokesperson for MEPCOM, told the news outlet Task and Purpose.

CBRN response Marines are trained to conduct precise detection, identification, and sampling of hazardous agents to protect personnel, preserve life, and support the attribution of weapons of mass destruction incidents. Freezing Winds is conducted to increase interoperability between Marines, Finland, and NATO Allies by executing combined amphibious operations in and around the Baltic Sea littorals, and is part of a regularly occurring series of exercises in northern Europe that demonstrates the capability to deploy and train Marines and Sailors in support of the NATO Alliance.

The list of disqualifying medical conditions includes sickle cell disease, peanut allergies, and both types of diabetes.
All three of these conditions, as some have noted, are quite common across the American populace, with peanut allergies being among the most common food allergies in the U.S., and diabetes becoming more common among the younger generation.
Other conditions that the new guidelines deem as “unlikely to be waived” include active cancers, Crohn’s disease, ligament ruptures in the last year, pacemakers, eczema, and many more. Also included in the list are mental disorders that require antipsychotic medications, or a diagnosis of Bipolar disorder.
Sifting Out Unqualified Recruits Earlier in the Process
Some have worried that these new guidelines may shrink the pool of potential recruits; however, this policy actually sifts out unfit candidates earlier in the recruitment process.
As Kate Kuzminski, from the Center for New American Security, explained, the policy “doesn’t actually narrow the candidate pool, since anyone with the listed conditions would be disqualified from military service in the end.” She then went on to explain that the new guidelines are intended to filter those “who ultimately couldn’t serve regardless,” thereby making it “fairer to the candidates themselves, sparing them the false hope.”

KAMANDAG is an annual Philippine Marine Corps and U.S. Marine Corps-led exercise aimed at enhancing the Armed Forces of the Philippines’ defense and humanitarian capabilities by providing valuable training in combined operations with foreign militaries in the advancement of a Free and Open Indo-Pacific. This year marks the eighth iteration of this exercise and includes participants from the French Armed Forces, Royal Thai Marine Corps, and Indonesian Marine Corps; including continued participation from the Australian Defense Force, British Armed Forces, Japan Ground Self-Defense Force, and Republic of Korea Marine Corps.

According to MEPCOM, the new policy also helps reduce unnecessary medical evaluations, enabling the service to focus its resources on applicants more likely to qualify for the military. “Instead of doing complete processing and then handing it to the waiver authority, we’ve created a trigger on the front end for these specific conditions that requires additional service sign-off, because all services agreed that they are unlikely to be waived on the back end,” Army Col. Megan McKinnon, the USMEPCOM command surgeon, said in the MEPCOM release. In other words, these measures not only save time and resources but also ensure that only qualified candidates are recruited.
Why the Armed Forces Need High Health Standards
The U.S. Armed Forces have always been particular about which conditions they can and cannot tolerate. Certain physical and mental conditions can have significant ramifications on the battlefield and, at worst, degrade a unit’s overall readiness. “The list of conditions isn’t surprising; the services always have to weigh the risks associated with either the presence of a condition or the lack of the ability to treat a condition on the battlefield when considering waivers, and they also have to weigh the potential costs associated with any given medical condition,” Kuzminski said.
The new policy, MEPCOM claims, is in line with a broader effort to increase the physical health of the U.S. Armed Services. For example, in July 2025, Secretary of Defense Pete Hegseth released a memo identifying 13 health conditions that automatically disqualify from military service, and another 13 that require special waivers from military officials.
Some of the waiverable conditions include ostomy, a history of kidney disease requiring dialysis, chronic liver failure, or a history of mood disorders like schizophrenia, delusions, or unspecified psychoses.
These measures are intended not only to ensure the mission readiness of the armed forces but also to ensure the health and safety of the soldiers on the battlefield.
The new guidelines imposed by MEPCOM do not match Hegseth’s memo one-for-one, but they do address similar issues, like heart conditions or a prior history of suicide attempts.
In the past, recruits who showed one of the 28 medical conditions would undergo medical and physical checks before being inevitably discharged. With the new policy in place, medically unfit candidates will now be disqualified much earlier in the process, thus saving time and resources.
The policy also comes as MEPCOM implements new AI prescreening tools to screen the health and physical records of new recruits.
