Providers who specialize in internal medicine focus on the healthcare needs of patients 18 and older, including maintenance and preventive care. Whether you are seeking a regular check-up or experiencing symptoms that you would like to consult with a professional about, an internal medicine specialist can help.

Internal medicine encompasses a wide range of health issues, from chronic diseases like diabetes and hypertension to acute illnesses such as infections and allergies. Our expert internists are here to provide personalized and compassionate care, ensuring your overall well-being.

Internal Medicine vs. Primary Care

Internal medicine is a specialized field within primary care. While primary care physicians treat a wide variety of health issues, internal medicine specialists focus exclusively on adult medicine. Internists undergo extensive training, equipping them with in-depth knowledge of complex diseases and adult health. This specialized expertise enables them to handle intricate cases and coordinate care for patients with multiple health concerns.

Preventive Care and Health Maintenance

At Catalyst Medical Group, we prioritize preventive care to maintain your health and well-being. Regular check-ups, immunizations, and screenings are essential components of our approach. Preventive services include:

  • Health screenings: Blood pressure checks, cholesterol screenings, and cancer screenings
  • Lifestyle counseling: Guidance on nutrition, exercise, stress management, and smoking cessation
  • Managing chronic conditions: Personalized plans to control chronic illnesses and prevent complications for conditions like diabetes, hypertension (high blood pressure), and asthma

When to Seek Internal Medicine Care

Consider consulting one of our experienced internists if you experience:

  • Chronic fatigue, unexplained weight loss, or ongoing pain
  • Multiple health issues that require coordinated management
  • Need for in-depth expertise in managing specific diseases or conditions

At Catalyst Medical Group, we understand the importance of timely and accurate diagnosis and treatment.
