1. Weight loss (BMI less than 29)
2. Treating nasal congestion and allergies aggressively
3. Treating GERD and heart burn aggressively
4. Positional therapy; sleeping on side
5. Evaluating and treating anemia and thyroid disease.
Ultimately, my recommendation is to see a sleep specialist who can clinically assess your mother's condition and treat appropriatley.
