Internal Medicine

Internal Medicine in Fort Myers, FL

Welcome to Tails-A-Waggin Animal Hospital & Pet Resort, where our veterinary team diagnoses and manages complex and chronic illnesses affecting your pet’s internal organs and systems.

Understanding Internal Medicine

Internal medicine focuses on diagnosing and treating conditions of the digestive, endocrine, respiratory, urinary, and cardiovascular systems. This often involves piecing together bloodwork, imaging, and clinical signs to identify conditions like diabetes, kidney disease, inflammatory bowel disease, or thyroid disorders.

Many internal conditions develop gradually and can be difficult to pinpoint without a thorough diagnostic workup. Our team uses on-site bloodwork, digital radiology, and ultrasound to get answers quickly, without unnecessary delays.

At Tails-A-Waggin Animal Hospital & Pet Resort, our internal medicine cases benefit from Dr. Mercado’s university-level diagnostic training and Dr. Báez’s surgical expertise when a condition requires more than medical management.

What to Expect During an Internal Medicine Evaluation

Our internal medicine workups in Fort Myers are methodical and thorough, so we can identify the true cause of your pet’s symptoms rather than just treating surface signs.

Detailed History & Physical Exam

We start with an in-depth conversation about your pet’s symptoms, diet, and history, followed by a complete physical exam to guide our diagnostic plan.

Advanced In-House Diagnostics

We use on-site bloodwork, urinalysis, digital radiology, and ultrasound to evaluate organ function and look for structural abnormalities, often providing same-day results.

Ongoing Disease Management

For chronic conditions like diabetes or kidney disease, we build a long-term monitoring and treatment plan, adjusting medications and diet as your pet’s needs change over time.

Why Internal Medicine Care Is Important for Your Pet

Internal conditions can be subtle and easy to miss without a structured diagnostic approach, making thorough internal medicine evaluation essential for pets with unclear or persistent symptoms.

Getting to the Root Cause

Symptoms like vomiting, weight loss, or increased thirst can stem from many different underlying conditions — proper diagnostics narrow down the true cause.

Preventing Complications

Conditions like diabetes and kidney disease can lead to serious complications if left untreated, but are often manageable with early, consistent care.

Coordinated Medical & Surgical Care

When a condition requires surgical intervention, our internal medicine and surgical teams work together under one roof.

Signs Your Pet May Need an Internal Medicine Evaluation

Contact us if your pet is showing any of these symptoms:

  • Increased thirst or urination
  • Chronic vomiting or diarrhea
  • Unexplained weight loss or gain
  • Persistent coughing or difficulty breathing
  • Ongoing lethargy or appetite changes

If your pet is showing any of these signs, please call us so we can begin a diagnostic evaluation.

How Often Are Internal Medicine Visits Needed?

Visit frequency depends on the condition being managed — some pets are seen for a single diagnostic workup, while others with chronic disease need ongoing monitoring every few months.
