Pickwickian syndrome and obesity hypoventilation syndrome are same. Actually person become so obese that brain loose control over breathing and because of so much fat deposit on chest wall...so hypoxia develops since person cannot take deep breathing. Eventually develops RHF symptums, acidosis, fall asleep during day.

Investigation and treatment involves: ABG, sleep studies, LFT, to rule out dd TFT,EEG,ECG( to rule out thyroid disorder, RHF, etc)
BiPAP, if needed mechanical ventilation, weight loss.
