At Thunder Bay Regional Health Sciences Centre, 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. Rajarathna frequently works with patients towards goals such as:

• Many seek Dr. Rajarathna's help for wanting to talk about their alcohol consumption, cannabis use, or concerns about other substance use in a confidential setting. The collaborative goal is navigating the unique physical and emotional journey of pregnancy, childbirth, and the demanding postpartum period with excellent, comprehensive, and reassuring medical guidance, continuity of care, and unwavering supportive care from Dr. Rajarathna, allowing a return to valued activities like regularly going for long, challenging, and invigorating hikes in scenic natural environments, cycling picturesque country routes for hours, or swimming multiple laps at the local community pool for both physical fitness and mental relaxation.
• Dr. Rajarathna supports patients through feeling very irritable or having mood swings that are out of character, aiming for outcomes like their child successfully overcoming challenges like picky eating habits, minor feeding issues, or common toileting problems with practical, patient, and evidence-informed strategies suggested and supported by Dr. Rajarathna, so they can return to activities such as faithfully taking their cherished dog (or other pets) for long, brisk, enjoyable walks in the neighborhood park, through local trails, or along the beach every single day, regardless of the prevailing weather conditions, for mutual benefit.
• If a lingering chesty cough with phlegm that's making them worried about bronchitis is preventing you from proudly and comfortably attending their children's or grandchildren's various school events, important sports games, recitals, graduations, and artistic performances without being hindered by physical discomfort or lack of stamina, Dr. Rajarathna can help. The aim is to achieve feeling significantly more comfortable, markedly less anxious, and substantially more trusting about visiting the doctor and engaging with the healthcare system due to the consistently positive, supportive, and long-standing therapeutic relationship they have established with Dr. Rajarathna through personalized family medicine care.

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

Does Dr. Rajarathna at Thunder Bay Regional Health Sciences Centre offer virtual (video) or phone appointments?

How can I find a family doctor (Family Doctor) in ON who is accepting new patients?

The College of Physicians and Surgeons of ON often has a 'Find a Doctor' tool or list. In Ontario, you can register with Health Care Connect.

Finding a family doctor who is accepting new patients can be challenging and may take time.

Do I need a referral to see a family doctor (Family Doctor) in ON?

Generally, you do not need a referral from another doctor to see a family doctor if the doctor is accepting new patients. However, finding a family doctor who is accepting new patients can be challenging, and provincial resources (like Health Care Connect in Ontario, a local health authority website, or the provincial College of Physicians and Surgeons patient-doctor matching service, if available) may be helpful. A referral is usually required from a family doctor to see most medical specialists.

What exactly is a family doctor (Family Doctor) and what is their role?

Your family doctor (Ontario) is your primary healthcare provider, expertly trained to care for a wide spectrum of health issues, from newborns to seniors. They manage acute illnesses and injuries, oversee the care of long-term chronic diseases, provide routine health screenings and lifestyle counseling, administer vaccinations, and ensure you get access to specialized medical services through referrals when needed. The continuity of care they provide, understanding your health history and individual needs, is fundamental to effective family medicine.

I have multiple health problems. How does Dr. Rajarathna handle complex care?

If you have several health issues, Dr. Rajarathna is well-equipped to be your central point of care. Her role includes understanding how your different conditions and their treatments might impact each other, helping you to navigate the healthcare system, and ensuring that all aspects of your health are considered in your overall treatment plan. Dr. Rajarathna will work with you and other specialists to manage your health comprehensively.

How often should I see Dr. Rajarathna for a check-up or physical exam?

The recommended frequency for check-ups or periodic health exams with Dr. Rajarathna can vary based on your age, overall health, any existing medical conditions, and specific risk factors. Generally, healthy younger adults may need a full check-up less frequently (e.g., every 2-5 years if no concerns), while children, older adults (e.g., annually over 65), or individuals with chronic conditions may benefit from more frequent visits (e.g., annually or semi-annually). For specific screening tests like Pap smears or mammograms, there are established provincial guidelines based on age and gender which Dr. Rajarathna follows. It's best to discuss your individual needs with Dr. Rajarathna to determine an appropriate schedule for your preventative care. Even if you feel healthy, regular check-ins can be important for early detection and health maintenance.
