Our Internal Medicine team is here for when detective work is required to establish a diagnosis
At Davies Veterinary Specialists, we recognise that in cases when there are no apparent surgical issues, it may be challenging to determine the exact cause of your pet’s illness. Therefore, our internal medicine specialists are here to help by understanding your pet’s illness. They may also go through your options and create a treatment plan that is specific to your pet’s needs.
Equipped for Excellence
At Davies Veterinary Specialists, we are proud of the advanced equipment and facilities we have under our premises that allow our internal medicine team to perform in-depth investigations. These investigations may include blood work, advanced imaging (such as ultrasound, CT scans and radiographs), and specialised procedures like endoscopy, all of which are essential for determining the underlying cause of the pet’s illness.
We are one of the biggest and most reliable veterinary specialists in the UK, and thanks to our team of specialists we can treat up to 10,000 patients every year! We are committed to excellence and to delivering amazing customer service, both for pet owners and our patients.
What Our Internal Medicine Team Can Help With
Our internal medicine specialists go beyond simply addressing common symptoms and offering standard treatments. We understand your pet’s needs and we take care of them as if they were our own by checking a wide range of internal medical conditions that may be affecting your pet’s organs and systems, including:
- Digestive Disorders: From acute diarrhoea to chronic inflammatory bowel disease, we offer comprehensive diagnosis and treatment plans for your pet.
- Endocrine Issues: We treat diseases including Addison’s, Cushing’s, and diabetes, making sure that hormone balance is maintained to keep their health up to date.
- Respiratory Problems: With expert diagnoses and treatment methods, we help your pet breathe easier by treating allergies, asthma, and other respiratory underlying conditions.
- Kidney and Liver Disease: We provide advanced care for these vital organs, monitoring function and implementing tailored treatment plans.
- Immunological Concerns: For your pet’s long-term health, we treat immune system illnesses.
- Oncology: We work together with our veterinary oncology specialists to offer comprehensive cancer diagnosis, staging, and treatment options, including chemotherapy.
Other common conditions that our team of specialists can delve deeper into include vomiting, diarrhoea, excessive drinking, malaise, weight loss or gain, anaemia and fever. All of which can be an internal medical matter.
Collaborative Approach
We understand the importance of collaborative work when it comes to your pet’s well-being, and this is why our internal medicine specialists work closely with other specialists’ team members at Davies, including those in diagnostic imaging, surgery, and anaesthesia, ensuring that we deliver a smooth and comprehensive approach to your pet’s care.
What to Expect During Your Visit
Typically, after an initial consultation, a patient will be admitted for further investigation such as blood tests, radiographs, ultrasound or endoscopy. After the tests, unless immediate additional treatment is needed, animals may go home to await results.
Sometimes, if a patient is found to have a non-medical disease and, for example, needs surgery or cancer treatment, they may be transferred to another team within the hospital. Our Internal medicine team can also help by offering:
- In-depth Consultations: During your pet’s internal medicine consultation, your referring veterinarian’s diagnostic tests can be thoroughly reviewed, together with your pet’s current symptoms and medical history.
- Comprehensive Examinations: To obtain a comprehensive examination of your pet’s health, we conduct not only a physical examination but also review any previous medical records available.
- Personalised Treatment Plans: Working together with you, we create a treatment plan tailored to your pet’s unique needs and diagnosis. This might include hospitalisation for further investigation or monitoring, outpatient medication, or a combination of both.
- Clear Communication: We make sure you are aware of your pet’s diagnosis and available treatments, and we keep you updated at every stage of the procedure.
- Aftercare Support: Following discharge, we offer comprehensive guidance and continuous assistance to make sure they will keep well and healthy.
