high blood pressure
"Been taking Atenolol many years.  I have an extremely difficult time keeping my weight down, bad metabolism.  I needed to increase the amount to 50 mg to get a good blood pressure of 120/70.  So now will probably gain weight.  Will change the extra 25 mg Atenolol to something else soon.   Wish I knew exactly what would work for the extra.  I am writing this after reading all the helpful comments here."
