Why Choose ACCESS Pasadena for Internal Medicine?

Internal medicine is where complex symptoms meet advanced diagnostics. Our board-certified internal medicine specialists work with skilled technicians, referring veterinarians, and other ACCESS specialty teams to evaluate challenging cases and build thoughtful treatment plans.

Our team can support pets with conditions involving the:

  • Gastrointestinal tract

  • Liver and pancreas

  • Kidneys and urinary system

  • Endocrine system

  • Respiratory system

  • Immune system

  • Blood and infectious diseases

When a pet’s case needs more than routine testing, our team digs deeper to find the answers to vague symptoms.

When Might a Pet Need an Internal Medicine Specialist?

Your veterinarian may recommend an internal medicine consultation when your pet has ongoing symptoms, abnormal lab results, or a condition that requires advanced medical management.

Pets may benefit from internal medicine if they have:

  • Chronic vomiting or diarrhea

  • Unexplained weight loss

  • Increased thirst or urination

  • Persistent coughing or breathing changes

  • Abnormal bloodwork

  • Liver, kidney, or pancreatic disease

  • Diabetes or other hormonal conditions

  • Immune-mediated disease

  • Fever or illness without a clear cause

Internal medicine is often helpful when your pet is sick, but the “why” is still hiding.

What to Expect During an Internal Medicine Consultation

Your pet’s visit begins with a detailed review of their medical history, symptoms, previous test results, and current medications.

Depending on your pet’s needs, our team may recommend:

  • Bloodwork

  • Urine and fecal testing

  • Ultrasound

  • Digital radiology

  • Endoscopy

  • Advanced imaging (CT, MRI)

  • Biopsy or tissue sampling

  • Additional specialized testing

After evaluation, your specialist will explain the findings, review treatment options, and communicate with your primary veterinarian so your pet’s care stays connected.

Coordinated Care for Complex Conditions

Many internal medicine cases require long-term management rather than a one-time answer. Our team focuses on clear communication, practical treatment plans, and ongoing collaboration with your primary veterinarian.

Some pets may need medication adjustments, recheck visits, additional testing, or support from another ACCESS specialty service. We help guide that process so you are not left trying to connect the dots alone.

If your pet needs advanced care for a complex medical issue, contact our team at (626) 993-9600 to schedule an internal medicine consultation.
