Internal medicine is about the same as primary care, but is also somewhat of a medical specialty. Internal medicine deals with the common and chronic conditions that typically affect adults and seniors, specifically. With internal medicine, a patient can get primary care services, like regular physical exams and prescriptions for medications, but also care for chronic conditions like arthritis or cystic fibrosis. Here at the clinic of Dr. Luis Mesa, Dr. Mesa is an internal medicine doctor who focuses on sleep disorders and pulmonary medicine in particular, but he is also fully capable of helping you with other conditions and your general health!
