5 Must Know Facts For Your Next Test

1. Nutritional deficiencies, such as low iron or vitamin B12, can contribute to shortness of breath by affecting oxygen transport.
2. Obesity can exacerbate shortness of breath due to increased demand on the respiratory system and potential for obstructive sleep apnea.
3. Malnutrition can weaken respiratory muscles, leading to an increased risk of experiencing shortness of breath.
4. In patients with chronic pulmonary illnesses like COPD, adequate nutrition is crucial for maintaining lung function and reducing episodes of dyspnea.
5. Hydration status impacts mucus production and viscosity; dehydration can make it harder for individuals with pulmonary issues to clear their airways effectively.
