What is Moyamoya Disease and How Does It Affect Blood Flow to the Brain?

Moyamoya disease is a rare, progressive cerebrovascular disorder characterized by narrowing or blockage of the internal carotid arteries at the base of the brain. As these arteries gradually become constricted, the brain receives less oxygen-rich blood. In response, the body develops a network of tiny collateral vessels to compensate. These fragile vessels appear like a “puff of smoke” on angiography — which is what the Japanese term “Moyamoya” describes.


Although these vessels temporarily help maintain circulation, they are weak and prone to rupture or clot formation.

Moyamoya can occur in both children and adults, but symptoms and progression patterns differ across age groups. Children commonly present with recurrent ischemic events or developmental delay, while adults are more likely to experience brain hemorrhage.

not hungry anymore

Hi, I hope you are all doing amazing.

since I started Syrona I am not hungry anymore, or at least way less.


I was never able to get under 72 kilograms, now I am 70.8 kilogram.

. I lost 10 kilograms. This is so amazing. And I still lose weight.

My goal for january was 70 kg and I feel I will pass that. My ultimate goal is 64 kg and I will I will reach that. I feel so thin now


I hoped Syrona will fix my eyesight, but that is not improved.
