For overweight patients it is considered a priority to aim for a normal weight. If the patient succeeds in shedding unhealthy excessive kilos, the night respiratory problem often disappears.
It can take months or even years, according to experience, until successful weight reduction is achieved. The introduction of necessary night breathing therapy should not be delayed. Under treatment with CPAP, a patient's weight decreases with his or her physical activity, without any need for a special diet.
