Rapper Rick Ross had to cancel a concert in Guyana on April 9 because he suffered another seizure — his third since October 2011. According to AllStarHipHop, the concert organizers said in a statement that the medical condition left the rap star unable to fly.

While some have speculated that his seizures may be a result from diabetes, Ross denies that is the reason and claims he is not diabetic. Last year in an interview with BET's 106th & Park, he said, "It was a case of me not getting enough rest, enough sleep."
Seizures are a result of abnormal electrical activity in the brain. Also known as "convulsions," a person suffering from seizures can shake uncontrollably. But it's important to note there are many types of seizures, some of which have mild symptoms in which there is no body shaking at all.

According to PubMed Health, here are some signs that someone may be having a seizure:

—Brief blackout followed by period of confusion (the person cannot remember a period of time)
—Changes in behavior such as picking at one's clothing
—Drooling or frothing at the mouth
—Eye movements
—Grunting and snorting
—Loss of bladder or bowel control
—Mood changes such as sudden anger, unexplainable fear, panic, joy, or laughter
—Shaking of the entire body
—Sudden falling
—Tasting a bitter or metallic flavor
—Teeth clenching
—Temporary halt in breathing
—Uncontrollable muscle spasms with twitching and jerking limbs

Most seizures last from 30 seconds to 2 minutes, and for the most part do not cause any harm. Seizures can occur for a range of reasons that range from being diabetic, having high fevers, suffering a head injury, suffering a stroke, having heart disease and being addicted to cocaine, to name a few. People who have recurring seizures due to a brain disorder have epilepsy.

If a loved one is having a seizure around you, the most important thing to do is to make sure they don't injure themselves. What to do:

—Try to lay them on their side and do not put anything in that person’s mouth.
—Stay with them until the seizure is over.
—Call 911 immediately if this is the person's first seizure, if they are pregnant, diabetic or injured, or the seizure lasts more than 2 minutes.
