From the Guidelines

The appropriate workup for a 65-year-old woman presenting with morning sweats should begin with a thorough history and physical examination to identify potential causes, including menopause-related symptoms, infections, malignancies, endocrine disorders, or medication side effects. Key elements of the history include asking about the timing, severity, and duration of sweats, associated symptoms, medication use, and recent life changes. Laboratory tests should include a complete blood count, comprehensive metabolic panel, erythrocyte sedimentation rate, thyroid function tests, and fasting blood glucose 1. Depending on clinical suspicion, additional tests may include a chest X-ray, tuberculosis testing, HIV testing, and hormone levels to assess for menopause-related symptoms. For women in this age group, morning sweats may be related to late menopause or post-menopausal hormone fluctuations, but it's crucial to rule out more serious conditions such as infections (tuberculosis, endocarditis), malignancies (lymphoma, leukemia), endocrine disorders (hyperthyroidism, diabetes), or medication side effects. If initial workup is negative but symptoms persist, further evaluation with imaging studies like CT scans or referral to specialists may be warranted. Treatment will depend on the underlying cause identified through this systematic approach.

Some key considerations in the workup include:

  • Assessing for menopause-related symptoms, as vasomotor symptoms such as hot flashes and night sweats are common in postmenopausal women 1
  • Evaluating for infections such as tuberculosis, which can cause night sweats, and considering testing such as a chest X-ray and sputum samples for acid-fast bacilli smear, mycobacterial culture, and nucleic acid amplification testing 1
  • Considering the possibility of malignancies such as lymphoma or leukemia, and evaluating for symptoms such as weight loss, fever, and fatigue 1
  • Assessing for endocrine disorders such as hyperthyroidism or diabetes, and evaluating thyroid function tests and fasting blood glucose levels
  • Reviewing medication lists to identify potential causes of morning sweats, such as certain antidepressants or blood pressure medications.

Overall, a thorough and systematic approach is necessary to identify the underlying cause of morning sweats in a 65-year-old woman, and to develop an effective treatment plan.

Morning Sweats in a 65-Year-Old Woman Workup

The workup for a 65-year-old woman presenting with morning sweats should consider various potential causes, including menopause, mood disorders, gastroesophageal reflux disease, hyperthyroidism, and obesity 2.

  • Initial Evaluation: A thorough history and physical examination are essential to identify any underlying conditions that may be causing the morning sweats.
  • Laboratory and Imaging Studies: If the initial evaluation does not reveal a specific cause, the following tests may be considered:
    • Complete blood count
    • Tuberculosis testing
    • Thyroid-stimulating hormone levels
    • HIV testing
    • C-reactive protein level
    • Chest radiography
  • Additional Tests: Depending on the results of the initial tests, additional studies such as computed tomography of the chest and/or abdomen, bone marrow biopsy, polysomnography, and/or additional laboratory studies may be considered 3.
  • Menopause: Menopausal symptoms such as hot flashes and night sweats may persist for 10 to 20 years or even longer, and hormone therapy may be considered in some cases 4.
  • Other Causes: Other potential causes of morning sweats, such as hematohidrosis, should also be considered, although these are rare conditions 5.
  • Age-Related Changes: While aging may affect various physiological processes, it does not appear to diminish the functional capacity of the sweating mechanism in healthy, active older women 6.
