Breathlessness

Definition

Breathlessness, also known as dyspnea, is the sensation of difficult or uncomfortable breathing. It can be caused by various factors including pulmonary conditions and poor nutritional status.

5 Must Know Facts For Your Next Test

1. Nutritional deficiencies, such as low levels of magnesium and potassium, can exacerbate breathlessness.
2. Obesity increases the workload on the respiratory system, leading to increased breathlessness.
3. Malnutrition can weaken respiratory muscles, further contributing to breathing difficulties.
4. High carbohydrate diets can increase carbon dioxide production, worsening symptoms in patients with chronic obstructive pulmonary disease (COPD).
5. Hydration status affects mucus viscosity; dehydrated individuals may experience thicker mucus, making breathing more difficult.
