Hi Dear ,
As per your query you have dizziness, lightheartedness and constipation . Well there can be many reasons for dizziness like ,
Low blood sugar and iron level , Some medications like anti-seizure drugs, antidepressants, sedatives and tranquilizers ,
Ear infection , Due to some medication , Benign paroxysmal positional vertigo , Meniere's disease and Migraine . Food allergy can also be one of the cause . I would suggest you to
consult ENT specialist for proper examination . Doctor may order certain tests like CT scan , blood test , rotatory chair test ,
posturography and examination with otoscope . Doctor may prescribe anti emetic drug , antibiotics (amoxicillin or penicillin ) at least for 10 days , antihistamine ,
Prochlorperazine and recommend vestibular therapy . For now do warm saline gargles and take steam twice daily .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
