chosen.content: Firstly, let's figure out what's going on here. The patient has symptoms of diabetes mellitus. He has polyuria (frequent urination), polydipsia (thirst), fatigue, and blurry vision. This could be due to hyperglycemia. To confirm that, we have to get a fasting glucose blood test. 
  
  Fasting means nothing to eat or drink for 8 hours before taking the sample. Fasting blood sugar levels are taken between 8-10 AM after 8 hours of fasting. It's usually taken in the morning because everyone fasts during the night. If the fasting blood sugar is normal, the next step is an HbA1c (hemoglobin A1C) test.
  
  An HbA1c test checks the percentage of sugar-coated red blood cells in the blood. The normal range is between 4.2% to 5.6%. Higher than that means diabetes is present.
  
  If it's high, Mark needs metformin. Metformin works by decreasing glucose production and increasing its absorption by the cells. It also lowers insulin resistance.
  
  Metformin is usually taken once daily in the morning. Some patients can tolerate twice daily dosing. But once daily on an empty stomach is standard. It can cause gastrointestinal side effects like diarrhea, nausea, vomiting, and stomach pain. It's not recommended to take it with food because it decreases its absorption.
  
  Another drug he might need is a SGLT2 inhibitor. They lower blood sugar by increasing glucose excretion in urine. This class of drugs includes Farxiga. Farxiga is taken once daily with or without food. It can cause genital infections.
  
  Lastly, Mark should consider lifestyle changes. Losing weight reduces diabetes risk. He should eat more vegetables, fruits, whole grains, low fat dairy products, poultry, fish, beans, peas, nuts, and seeds. He should limit red meat, saturated fats, trans fats, and sodium. He should avoid sugary drinks, sugar, and red and processed meats. Regular exercise improves blood sugar control. He should aim for at least 30 minutes of moderate physical activity most days of the week. He should avoid smoking. He should have his blood pressure checked regularly. He should check his blood sugar at home if prescribed.
  
  Here's a summary:
  - Fasting blood sugar test
  - HbA1c test
  - Metformin (once daily)
  - SGLT2 inhibitor (once daily)
  - Lifestyle modification
  
  Good luck Mark!
