Hi, your persisting symptoms of bloating, nausea and dizziness could indicate a viral gastroenteritis. Lack of proper nutrition can cause dizziness due to hypoglycemia. The other causes could be jaundice if there is yellowish discoloration of skin, food poisoning if the symptoms occurred shortly after taking food, peptic ulcer disease and sometimes cholecystitis and pancreatitis. Please consult your primary care physician at the earliest for evaluation. Regards.
