Philippine President Rodrigo Duterte reveals he suffers from autoimmune disease myasthenia gravis
- The condition causes muscle weakness, and can result in drooping of eyelids, blurred vision as well as weakness in one’s extremities
- Duterte has also said previously he suffers from daily migraines and ailments including Buerger’s disease, an illness that affects the veins and arteries of limbs

Duterte, 74, was the oldest person to be elected president of the country and questions about his health have swirled since taking office in 2016.
His occasional skipping of events and meetings, as well as him discussing his ailments, has only added to the speculation.
“One of my eyes is smaller. It roams on its own,” he said, according to a transcript released on Sunday by his office. “That’s myasthenia gravis. It’s a nerve malfunction. I got it from my grandfather.”
The condition causes muscle weakness, and can result in drooping of eyelids, blurred vision as well as weakness in one’s extremities, according to the US National Institutes of Health.

The condition can generally be managed with treatment, but up to 20 per cent of people who have the disease experience at least one “crisis” that requires them to use a ventilator to help breathe, the NIH said.
