who functional classification of pulmonary hypertension

The World Health Organization categorizes pulmonary arterial hypertension into four functional classes to evaluate the severity of the condition and its effects on daily activities. These classes span from Class I, the mildest, to Class IV, the most severe.

Class I is the least severe, where patients may be asymptomatic or only experience mild shortness of breath during strenuous activities. Class II signifies the onset of symptoms such as shortness of breath, fatigue, or palpitations during light to moderate daily activities. Class III is characterized by significant shortness of breath during routine activities, potentially curtailing their mobility. Lastly, Class IV denotes the most critical stage, with patients experiencing shortness of breath even at rest, and any physical exertion can lead to a worsening of symptoms.

For individuals with pulmonary arterial hypertension, regular medical check-ups and adherence to the physician's treatment regimen are advised. Additionally, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and abstaining from smoking, can aid in managing the disease. Remember, always follow your doctor's instructions when taking medication and never self-administer drugs without guidance.
