What causes dizziness and blurred vision during weight loss?

Dizziness and lightheadedness during weight loss may be caused by the following factors: 1. Malnutrition: Excessive dieting or an unbalanced diet during weight loss can lead to inadequate nutrient intake, resulting in anemia or hypoproteinemia, which may impair normal blood and oxygen supply to the brain and cause dizziness. 2. Hypoglycemia: Prolonged fasting or excessive exercise may trigger low blood sugar, reducing blood glucose levels and causing symptoms such as dizziness and palpitations. 3. Medication side effects: If weight loss is achieved through weight-loss drugs, dizziness and lightheadedness may result from drug side effects, especially when the medication is of poor quality or taken in excess. If dizziness or lightheadedness occurs, prompt medical attention is recommended to identify the underlying cause and receive appropriate treatment.
