[25F] Experiencing rapid weight loss and night sweats

What might be happening

Based on the symptoms you've described, there are several possibilities:

• Infection: Certain infections can cause symptoms such as rapid weight loss, lack of appetite, exhaustion, night sweats, and muscle soreness. These could include viral infections like HIV, or bacterial infections like tuberculosis.

  • Treatment would depend on the specific infection, but could include antibiotics or antiviral medications.

• Cancer: Although less likely at your age, certain types of cancer can cause similar symptoms. Lymphoma, for example, often causes night sweats, weight loss, and fatigue.

  • Treatment would typically involve chemotherapy, radiation, or surgery.

• Endocrine disorders: Conditions such as hyperthyroidism or Addison's disease can cause weight loss, fatigue, and other symptoms.

  • Treatment would typically involve hormone replacement therapy.

• Mental health conditions: Conditions such as depression or anxiety can cause a loss of appetite and fatigue.

  • Treatment would typically involve therapy and/or medication.

• Malabsorption: Given your history of a duodenal switch, it's possible that you're not absorbing nutrients properly, which could cause weight loss and fatigue.

  • Treatment would typically involve dietary changes and possibly supplements.

What you can do

Given the severity and duration of your symptoms, it's important to see a healthcare provider as soon as possible. They can perform a physical examination and order tests to help determine the cause of your symptoms. In the meantime, try to stay hydrated and eat small, frequent meals if you can.

What you should look out for

Seek immediate medical attention if you develop any of the following:

• Severe abdominal pain
• Blood in your stool or vomit
• A fever over 100.4°F
• Difficulty breathing
• Confusion or difficulty staying awake
