Hi thanks for asking question in healthcare magic.
The diarrhea with weakness here may be due to
hyperthyroidism like case.So rule out hyperthyroid by thyroid profile.
Avoid stress , as it might shoot blood pressure.
Rule out kidney conditions by renal function test.as kidney disease might lead
secondary hypertension.
For hip problem it might be
arthritis or osteoporotic changes.X ray done for it.Vitamin D or calcium may needed.
Whenever you it excess you suffer diarrhea becoz of
indigestion and removed
gall bladder.Fatty food should be taken minimum by you.
Control blood pressure by low salt diet, regular exercise, yoga , less fatty food etc.
Sometimes as while consulting doctor because of stress white coat hypertension might present.
I hope your concern solved.
Take care
