Hi,
Drowsiness & sluggish feeling is commonly due to
Hypoglycemia,
Dehydration, Vertigo,
Iron deficiency anemia, Inadequate sleep(insomnia), Developing Neurological or CAD, coronary artery disease (faster irregular heart beats).
You are suggested to visit ER & get a complete medical check up done. You may have to get CBC (F, PP, Hb%), Urinalysis, Lipid profle, ECG,
Echocardiography,
Stress test, Nerve Conduction tests, required Imaging tests to rule out neurological, CAD & any other pathology causing the discomfort. To rule out Vertigo get audiometry & middle ear examination done.
Your treatment will depend upon the severity of the pathology detected. In the meantime take adequate sleep, stay away from stress, take home made food avoid high purine diet. Do regular exercises & stay hydrated.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K,
