Your mother needs to get examined to rule out a few things such as low blood pressure, postural hypotension, cervical spinal nerve compression, hypoglycemia, severe anemia, an underactive thyroid (called hypothyroidism), overactive thyroid (called hyperthyroidism), adrenal insufficiency (called Addison's disease), GERD, and
internal ear infections. FSH, LH, estrogen and
progesterone should also be tested.
Please consult your PCP for primary examination followed by proper referral.
