Premature labour: Also known as preterm labour, occurs when regular contractions and relaxations of the uterus result in the opening of your cervix after week 20 and before week 37 of pregnancy. It can lead to premature birth and other greater risk to the baby.

Cerebrovascular insufficiency: It occurs when there is obstruction of one or more blood vessels (arteries) that supply blood to the brain. This obstruction leads to strokes or transient ischemic attacks (TIAs or 'mini-strokes').

Buerger's disease: Buerger's disease occurs commonly in the arms and legs where blood vessels get swollen, thereby preventing blood flow, causing clots to form. This leads to pain, tissue damage, and the formation of gangrene (death of body tissues).

Raynaud's phenomenon: Raynaud's phenomenon occurs due to blocked nerves resulting in discolouration of the fingers and/or the toes after exposure to extreme cold or hot temperatures conditions. Skin discolouration shows a diminished blood supply to the local tissues.
