Effective management of health is key to well-being in later life. Dr. Markus Sonntag provides expert, compassionate care for a range of conditions common in older adults, with a focus on managing symptoms and maintaining function. Common areas of focus include:

  • Cachexia: Cachexia, characterized by significant muscle loss and weakness, can be effectively managed with a combination of nutritional support and medical treatments to help you maintain your independence.
  • Leukocytopenia: Leukocytopenia is a condition where you have a lower than normal number of white blood cells, which are crucial for fighting infections, and managing it often involves addressing the underlying cause to help you stay healthy and active.
  • Perimenopause: The years leading up to menopause, known as perimenopause, involve changes in hormone levels that can cause symptoms like irregular periods, mood swings, and decreased energy; managing these symptoms effectively can help maintain independence and improve overall health during this time.
  • Vitamin B12 Deficiency: A lack of vitamin B12 can lead to problems with your nerves and blood, causing symptoms like tiredness and memory issues; thankfully, regular B12 injections or supplements can often restore your vitality.
  • Prostatitis: For men, prostatitis is an inflammation of the prostate that may lead to urinary issues and pelvic pain. Treatment options are available to reduce symptoms, making everyday activities easier and more comfortable.
  • Obesity: Having a higher than recommended body fat percentage, called obesity, can impact your health, but through a combination of lifestyle changes and, if needed, medical interventions, you can take control and feel better.
  • Sleep-Related Leg Cramp: Treatment for leg cramps can include over-the-counter pain relievers, muscle relaxants, or addressing vitamin deficiencies to reduce nighttime pain and improve your quality of life.
  • Chronic Fatigue Syndrome: Living with Chronic Fatigue Syndrome requires patience and understanding, and treatment plans often involve a team approach with doctors, therapists, and support groups, leading to better overall well-being.
  • Shortness of Breath: If you're experiencing shortness of breath, don't hesitate to seek medical attention; with proper diagnosis and treatment, you can maintain your independence and enjoy a better quality of life.
  • Pharyngitis: A sore throat, medically known as pharyngitis, can be uncomfortable, but thankfully, many cases clear up on their own with home care like staying hydrated and resting your voice.
  • Limb Swelling Caused by Fluid Overload: Fluid overload causes swelling in your arms and legs, making everyday tasks difficult, but treatments like diuretics can reduce the swelling and improve your mobility and quality of life.
  • Throat Pain: Throat pain can be caused by various factors, from a simple viral infection to more serious conditions; consulting your doctor for diagnosis and treatment ensures appropriate care and improves your comfort level.

This list highlights some common health concerns and is for informational purposes. An accurate diagnosis and a personalized care plan can only be developed through a direct consultation with a qualified medical professional based on your specific health history.
