You have to be fat to have high cholestrol levels.
I remember one of my old bosses, a thin lady with barely an appetite. Turns out she was a prime candidate for cholesterol treatment. Why? She had high cholestrols in her blood stream, and it seemed weird, at the time.
A common assumption about cholestrol is that you have to be fat to have poor cholestrol: that lady clearly was not fat. Yet she was required to take cholestrol medication to reduce her LDLs to a reasonable level.
Asthma means you can’t breath
While you may have breathing difficulties, one of the most common signs of asthma is the coughing. Yet most people assume a person with a cough has flu or a cold or that asthma means breathlessness. Not always true.
There are lots of medical assumptions we, as untrained and unknowledgable individuals, make every day regarding our own health and that of those around us. Care to add one?
