What is the diagnosis for a 57-year-old female with a history of diabetes mellitus, chronic kidney disease (CKD), hypertension, and hyperlipidemia, presenting with fatigue, weakness, myalgia, headache (HA), and dyspnea on exertion after initiating Jardiance (empagliflozin) and Rybelsus (semaglutide) for uncontrolled diabetes, with improved blood glucose levels and taking Tylenol (acetaminophen) Cold and Flu?

Differential Diagnosis

• Single most likely diagnosis + Viral upper respiratory infection: The patient's symptoms of fatigue, weakness, body aches, headache, and scant clear nasal drainage are consistent with a viral upper respiratory infection, which is a common and self-limiting condition. The recent use of over-the-counter Tylenol Cold and flu also supports this diagnosis.
• Other Likely diagnoses + Diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS) due to medication change: Although the patient's blood sugars have improved with the new medications, it's possible that the rapid change in glucose control could lead to a metabolic disturbance. However, the patient's current blood sugar range (118-124) makes this less likely. + Medication side effects (Jardiance or Rybelsus): The patient recently started new medications, and it's possible that the symptoms could be related to side effects such as dehydration or hypoglycemia, although the patient's current blood sugar range is not suggestive of hypoglycemia. + Dehydration: The patient's symptoms of heavy breathing with exertion and fatigue could be related to dehydration, especially if she has been experiencing increased urination due to the new medications.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.) + Pulmonary embolism: Although the patient's symptoms are not typical for pulmonary embolism, the presence of heavy breathing with exertion and fatigue warrants consideration of this potentially life-threatening condition. + Sepsis: The patient's chronic medical conditions (diabetes, chronic kidney disease, hypertension, and hyperlipidemia) put her at increased risk for infections, and sepsis is a potentially life-threatening condition that requires prompt recognition and treatment. + Cardiac ischemia or myocardial infarction: The patient's symptoms of heavy breathing with exertion and fatigue could be related to cardiac ischemia or myocardial infarction, especially given her history of hypertension and hyperlipidemia.
• Rare diagnoses + Influenza: Although the patient's symptoms are consistent with a viral upper respiratory infection, influenza is a less likely diagnosis given the lack of specific symptoms such as fever, cough, or sore throat. + Pneumonia: The patient's symptoms of heavy breathing with exertion and fatigue could be related to pneumonia, although this would be an uncommon presentation without other symptoms such as cough, fever, or chest pain.
