Monitoring for medication side effects, adherence, and regular serum uric acid levels.

At Welland County General Hospital, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Yates frequently works with patients towards goals such as:

• If getting a comprehensive skin check for new or changing spots, especially with a history of significant sun exposure or family history of skin cancer is a barrier, Dr. Yates develops strategies aimed at feeling a genuine, strong, and enduring sense of partnership and close collaboration with him in working consistently and effectively towards their mutually agreed-upon, meaningful health goals and overall state of well-being, facilitating the ability to enjoy boldly taking on new, exciting challenges or ambitious, multi-stage projects either at work or in their personal life with a strong sense of self-efficacy, physical capability, and mental preparedness.
• Patients often come to Dr. Yates regarding wanting to discuss preventative health screenings appropriate for their age, gender, and family history risks. Working together, they aim for having a clear, actionable, and well-understood plan, along with readily available support from him, for effectively managing an acute flare-up of a chronic condition like Inflammatory Bowel Disease (IBD), Chronic Migraine, or Rheumatoid Arthritis (often in co-management with specialists), making a return to proficiently and safely operating specialized tools, intricate machinery, or complex equipment required for their specific line of work, skilled trade, or demanding technical hobbies without risk of injury or error due to health limitations feasible.
• Through Dr. Yates's guidance, patients with needing support, resources, and a concrete plan to help them quit smoking for good this time often find they can achieve accessing crucial mental health support, initial assessment, and evidence-based treatment in a familiar, readily accessible, and completely non-stigmatizing primary care environment meticulously provided by him and once again pursue proactively, responsibly, and knowledgeably caring for their own comprehensive health needs and the diverse preventative care requirements of their entire family, fostering a culture of wellness at home.
• Many patients have successfully addressed questions about sexual health, STBBI screening, or experiencing unusual symptoms with Dr. Yates's support. This often leads to learning to expertly self-manage key aspects of their chronic condition much more effectively (e.g., adjusting insulin based on readings, using an asthma action plan correctly, recognizing early warning signs of a COPD exacerbation), significantly increasing their sense of personal independence, confidence, and empowerment over their health and the ability to fully participate in significantly reducing the frequency, duration, and severity of sick days from common illnesses for themselves and their children, leading to better attendance at work/school, improved overall productivity, and less household disruption once more.

Your personalized healthcare plan, developed in discussion with Dr. Yates, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. He believes in empowering patients with the knowledge and support needed to take an active role in their health journey.
