Internal Medicine for Dogs & Cats in Bethalto, IL | Bethalto Animal Clinic

Some health issues are easy to spot. Others take a little detective work.

If your dog or cat is drinking more water than usual, losing weight, experiencing digestive issues, or simply not acting like themselves, an underlying medical condition may be the cause. Internal medicine focuses on diagnosing and managing diseases that affect the body’s internal systems, helping pets live healthier and more comfortable lives.

At Bethalto Animal Clinic, our veterinary team provides personalized care for dogs and cats facing chronic or complex medical conditions. As a family-owned practice that has served Bethalto for nearly 50 years, we take a practical, thorough approach to finding answers and creating treatment plans that work for both pets and their families.

What Is Veterinary Internal Medicine?

Veterinary internal medicine focuses on conditions affecting organs and body systems such as the kidneys, liver, bladder, endocrine system, and more. These cases often require advanced diagnostics, ongoing monitoring, and long-term management.

Many internal medicine conditions develop gradually, making regular wellness exams an important part of early detection.

Signs that may indicate an underlying medical condition include:

  • Increased thirst or urination
  • Weight loss
  • Changes in appetite
  • Vomiting or diarrhea
  • Lethargy
  • Behavioral changes
  • Weakness
  • Poor coat condition
  • Frequent urinary accidents

If you’ve noticed any of these symptoms, our veterinary team can help determine the cause and recommend the next steps.

Diabetes Management

Diabetes mellitus occurs when the body cannot properly regulate blood sugar levels. While diabetes requires lifelong management, many pets continue to enjoy a happy and active life with the right treatment plan.

Common signs of diabetes include:

  • Increased thirst
  • Increased urination
  • Weight loss
  • Increased appetite
  • Low energy

Our veterinary team provides:

  • Diagnostic testing
  • Blood glucose monitoring
  • Insulin therapy guidance
  • Nutritional recommendations
  • Ongoing recheck examinations

We work closely with pet owners to make diabetes management as straightforward and manageable as possible.

Bladder and Urinary Tract Disorders

Urinary conditions can be painful and frustrating for pets. Prompt diagnosis often leads to faster relief and helps prevent complications.

We evaluate and manage conditions such as:

  • Urinary tract infections
  • Bladder inflammation
  • Urinary crystals
  • Bladder stones
  • Chronic urinary disease

Signs of urinary disease may include:

  • Urinating more often than normal
  • Difficulty or discomfort while urinating
  • Blood visible in the urine
  • Having accidents indoors
  • Excessive licking around the genital area

If your pet is having difficulty urinating, contact us right away. In some cases, urinary problems can become emergencies.

Kidney Disease Diagnosis and Treatment

Kidney disease is commonly seen in aging dogs and cats, though it can affect pets of any age.

Because the kidneys play a major role in filtering waste and maintaining hydration, declining kidney function can affect a pet’s overall health.

Common symptoms include:

  • Increased drinking
  • Increased urination
  • Weight loss
  • Poor appetite
  • Vomiting
  • Fatigue

Routine blood work and urinalysis often help identify kidney disease before symptoms become severe. Early diagnosis allows for more effective long-term management and can help maintain your pet’s quality of life.

Liver Disease Evaluation and Management

The liver performs many essential functions throughout the body, including digestion, metabolism, and toxin removal.

When liver disease develops, symptoms can vary widely and may include:

  • Decreased appetite
  • Vomiting
  • Weight loss
  • Increased thirst
  • Lethargy
  • Jaundice (yellow discoloration of the skin, gums, or eyes)

Our veterinary team uses diagnostic testing to identify the underlying cause and develop an individualized treatment plan based on your pet’s specific needs.

Oncology Consultations

A cancer diagnosis can leave pet owners with a lot of questions. Our veterinary team helps guide families through the next steps by evaluating your pet’s condition and discussing available treatment options.

During an oncology consultation, we may discuss:

  • Diagnostic findings
  • Additional testing recommendations
  • Treatment options
  • Expected outcomes
  • Quality-of-life considerations
  • Referral recommendations when appropriate

Every case is different. Our goal is to provide clear information so you can make informed decisions about your pet’s care.

Diagnostic Testing for Internal Medicine Cases

Finding the root cause of a medical problem often requires more than a physical examination alone.

Depending on your pet’s symptoms, we may recommend:

  • Blood testing
  • Urinalysis
  • Diagnostic imaging
  • Ongoing laboratory monitoring
  • Follow-up examinations

These tools help us gather important information about how your pet’s body is functioning and allow us to make treatment recommendations based on objective findings.
