Weight loss, especially dieting, often leads to malnutrition, even hypotension, anemia and other symptoms, and therefore can manifest as dizziness. Treatment for this condition suggests resuming a normal diet and monitoring blood pressure, hemoglobin, red blood cells and other values. If hypotension or anemia is present, corrective treatment can be actively carried out by taking Bajhen granules or Shengve drink oral solution to relieve the symptoms. The best way to lose weight is to exercise and control the diet, eating less fatty food, but eating three meals a day normally to avoid malnutrition or anemia, hypotension and other diseases caused by dieting.
