3. Hypertension Due to Lung Diseases and Hypoxia

Hypertension due to lung diseases and hypoxia refers to high blood pressure in the lungs caused by problems such as chronic obstructive pulmonary disease (COPD) or sleep apnea. When the lungs are damaged or not functioning well, they can't provide enough oxygen to the blood, leading to low oxygen levels (hypoxia). This can cause the blood vessels in the lungs to narrow, making it harder for blood to flow and increasing pressure. Over time, this can strain the heart and lead to pulmonary hypertension, which can cause symptoms like shortness of breath and fatigue.
