Sleep medicine has also emerged as a prominent area of internal medicine with the increasing recognition of its role in chronic diseases like cardiovascular disease, diabetes, and psychiatric disorders. Insomnia, obstructive sleep apnea, and disturbance of the circadian rhythm are common presentations encountered by internists.
Diagnostic and treatment innovations, such as home sleep testing and CPAP alternatives, enhance access as well as therapy adherence. By treating sleep health as an integral aspect of patient care, internal medicine doctors not only enhance quality of rest but also reduce risks of long-term systemic diseases.
