29 Bizarre Medical Conditions You’ve Never Heard Of

Medical Conditions

We have all had a medical condition at one point in our lives. For most people, it is something simple like a cold, the flu or poison ivy. For others, the conditions are much more serious, such as cancer or heart disease. Some people have very rare conditions. Here are 29 bizarre medical conditions you’ve never heard of.

Cotard’s Syndrome

In severe cases, people have died of starvation from this disease because they think that they don’t need to eat anymore since they are dead.

This condition is caused by brain lesions, and it can cause you to want to have sexual relations with inanimate objects, like a car or a shoe. Other symptoms include hypersexuality with other people, overeating, and licking things in public.

Fish Odor Syndrome

This is a rare metabolic disorder that causes a buildup of a specific enzyme that causes your sweat and breath to smell like fish. What makes this condition even more strange is that the person who has it cannot smell themselves, and the odor won’t go away no matter how many times they shower.

Alien Hand Syndrome

People with this condition believe that their limbs are acting on their own and find themselves trying to restrain the “alien hand.”

Gourmand Syndrome

A stroke or a head injury can cause a person to become a gourmet foodie suddenly. A Swiss political journalist became a food critic after a stroke.

People who suffer from this condition hear a loud bang right before drifting to sleep. It occurs in 10 percent of people, and it affects women more often than men.

Prader-Willi Syndrome

Paris Syndrome

This condition affects people who weren’t impressed with Paris. The symptoms include dizziness, hallucinations, delusional feelings, and heart palpitations.

This very rare genetic disorder is a form of insomnia that gets progressively worse. Over time, it leads to hallucinations, dementia, and it always results in death.

The cause is unknown, and there is no treatment. Fortunately, it doesn’t cause any pain or discomfort.
