For optimal management of pulmonary hypertension, it is crucial to adhere to specific dietary and lifestyle guidelines. Limit your daily sodium intake to a maximum of 2,000 milligrams and fluid consumption to approximately 8 glasses. Avoid high-sodium foods such as fatty, fried, canned, frozen, and fast-food items. Instead, prioritize a diet rich in fresh fruits, vegetables, whole grains, lean meats, and fish, while minimizing added fats and sugars. Furthermore, maintaining good sleep hygiene is essential. Conditions like sleep apnea, which impede proper breathing during sleep, can significantly worsen the prognosis of pulmonary arterial hypertension (PAH).
