From a medical point of view, women suffer more and more diseases than their male counterparts. First of all, as far as physical diseases are concerned, let’s not mention the well-known gynecological and breast diseases. Some diseases “prefer” women, such as peripheral vascular disease in the multiple arteritis, the prevalence of women than men, about 7:1 ~ 8:1, and the peak incidence of women in their 20s, men do not have the peak age. Raynaud’s syndrome: the ratio of men to women is 1:10, and the age of onset is mostly between 20 and 40 years old. Hand-foot cyanosis: it is more common in young women, and the age of onset is mostly between 20 and 45 years. Simple purpura among vascular purpura, also known as female-prone cyanosis syndrome, is predominant in young women. Autologous erythropoietic purpura is only seen in middle-aged women. Autologous DNA-sensitizing purpura is seen mostly in females. Systemic lupus erythematosus (SLE) is significantly higher in women than in men, and is more common in women of childbearing age, with a female to male ratio of (7-9):1. rheumatoid arthritis (RA) has a female to male ratio of 3:1. hyperthyroidism has a male to female ratio of 1:4-6, and thyroid adenocarcinoma has a male to female ratio of 1:3. chronic fatigue syndrome is 5 times more common in women than in men. Multiple sclerosis is 2 to 3 times more common in women than in men. The above does not include the more common gestational hypertension, gestational diabetes, etc. that women suffer from during special periods.
