COMMON MEDICAL CONDITIONS THAT MIGHT DISQUALIFY YOU FROM JOINING THE MILITARY

There are some pretty unusual medical conditions that can disqualify you from serving in the military.

In order to join the military you need to qualify medically. And while there are some obvious stipulations, like the fact that you can’t be carrying diseases that will endanger your platoon, there are other disqualifying conditions that might surprise you.

These are common likely medical conditions that might disqualify you.
Note: it varies country by country.


You can’t have flat feet.
Though this is one of the most widely argued-about conditions that can bar you from the military, the answer is yes — it is real. While someone who has flat feet can serve in the military, it depends on the severity. If someone has “symptomatic” flat feet, which indicates that the condition causes the person chronic physical pain, then he or she cannot serve.
Your butt can’t be too big.
Spinal disorders and conditions are taken very seriously by the military. Many of the jobs have stringent physical demands and standards, and having any sort of back issue can be detrimental to your health, and the readiness of the force.
You need to take care of your teeth.
Your dental health is very important when joining the military; you can’t have too many cavities. IT will disqualify you from service. Having braces can also temporarily disqualify you, also.
Your testicles have to be … normal.
You have to have normal genitalia to be in the military. Too big or Too small can be a problem, Absence of one or both testicles, whether congenital, acquired, or unexplained absence of a testicle is also unacceptable according to military standards.

You can’t Have Ta too,
This varies from the kind of Country you live in
Mostly in African countries, like here in Nigeria, Tattoo is a big no for military candidates.

You can’t have eczema or acne.
Despite the fact that the dry-skin rash and the oily-skin condition aren’t contagious, you can’t have either and join the military. Eczema — though it can be maintained with prescription — can also be debilitating. It’s dry, itchy, and it spreads. Acne, on the other hand, runs the gamut from requiring antibiotics to interfering with proper wear of a gas mask.
But there is hope in certain cases. 
You cant have a recent fresh surgery or deep scar


In certain cases, and in the event that you have a good Military exam score and selection points, a medical waiver option is available. For some, certain military board selectors will work with you and advocate on your behalf in certain instances where they believe your condition won’t interfere with your service.

There are many more but they varies country by country, The list up here is a common factor in African military institutions. Also note that not in all circumstances you might be disqualified because of this, there are always miracle but just happen in few times.

Although its a nice thing to use a private hospital to check oneself before going for any military selection  screening, but if you can access a military hospital before that, its going to make sense a lot as they are experienced in what will be checked  or  not, what qualifies and what disqualify, discuss with the doctor. It saves yo stress of eviction in the real military medical screening you will be going for.
