Hello and welcome to HCM.
I understand the various health problems you must be facing.
Considering your clincal scenario,medications and post menopausal age,I recommend-
-Continue taking your routine medications as prescribed,weight gain can be because of tablet Paxil,but that is not indication for stopping the drug.
-Advice blood investigations like thyroid test,blood
glucose,
blood lipids.The symptoms you mentioned can be because of
thyroid disorder,
diabetes mellitus etc
-Menopausal symptoms itself may cause such clinical picture.Adopting just a healthy lifestyle will help.Balanced diet including lots of vegetables,fruits,dairy products;regular brisk walking of 30 minutes minimum,wear loose clothing,engaging yourself in some hobby or medication and yoga ;taking vitamin and
calcium supplements ,all these measures will help a lot.
Hope this information helps.
Thanks and regards.
