My mother didn't feel well last weekend. she just went to the dr. for a stress test and right when she got home she yelled and was nasty had anger?

Beware: Stress Tests: totally miss arterial disease until after advanced & complications (plaque ruptures & resulting scared down clots) have created narrowings (stenoses of typically >75%) BEFORE they are capable of detecting ANY abnormality. Exercise EKG type most sensitive; Nuclear stress much less so (despite promotion, for money, to the contrary). She may have been angry at how treated; this could be appropriate.

Not the stress test: Stress test does not cause "stress" in the usual sense of the term. If you mother was upset, you should ask her why she behaved the way she did. There are likely other issues affecting her attitude. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
