Adult medical care that looks at the complete clinical picture.
Internal medicine connects symptoms, medical history, medications, laboratory trends, risk factors, and long-term conditions.
Adult Medical Expertise
What Is an Internal Medicine Doctor?
An internal medicine doctor, also called an internist, specializes in preventing, evaluating, and managing health concerns in adults. Internists are trained to consider how different symptoms, conditions, medications, and risk factors may affect one another—especially when a patient has more than one ongoing medical concern.
At IASIS, Dr. Karanastasis combines internal-medicine expertise with a membership model that allows more time for careful discussion and follow-up. Patients seeking routine care can also explore adult primary care in Orland Park.

When Internal Medicine Helps
Comprehensive Care for the Health Concerns Adults Face
Internal medicine is valuable when medical decisions require a broad understanding of your history, risks, medications, and changing health needs.
Multiple Conditions
Manage overlapping adult health concerns with one physician who can consider how each condition affects the broader plan.
Medication Review
Review treatment response, side effects, possible interactions, duplicate therapies, and questions about medications from specialists.
Risk Assessment
Evaluate personal and family history, laboratory trends, blood pressure, metabolic health, and cardiovascular risk.
Ongoing Monitoring
Follow changes in symptoms, measurements, medications, and laboratory results instead of treating every visit as an isolated event.
Specialist Coordination
Understand when specialist evaluation may be appropriate and how outside recommendations connect to your overall medical plan.
