An 18-year-old girl was taken to the hospital with high blood pressure and headaches. doctors noticed that she looked very thin and discovered she had a heart problem. after talking with her, the doctor discovered that her symptoms were caused by dieting. which type of diet would most likely cause these types of difficulties? a. fasting diets b. low-carbohydrate diets c. diet pills d. diuretics

By examining this Question, I can say that option 1, or A, would fit the best, because if you are fasting, very long, or after fasting you start eating a lot, after you have not been eating, that really makes big trouble for your health. as well to all that, i would add that in my own experience, i used to fast like 1 day, and in the evening, if I eat a lot, that really makes me dizzy, or even i get a head ache quick.
Hope that my answer would help you! =)
Have a great day! =)

I would think A. Fasting diets because if your fasting and not fasting "properly" your health can go very bad and can cause heart related troubles.
