Several medical conditions can impair sexual function in older adults:

Cardiovascular Diseases – Reduced blood flow due to hypertension or atherosclerosis can cause erectile dysfunction (ED) or vaginal dryness.
Diabetes Mellitus – Nerve damage and poor circulation can lead to ED and reduced sexual sensation.
Hormonal Imbalances – Lower estrogen or testosterone levels affect libido and arousal.
Neurological Disorders – Conditions like Parkinson’s disease, multiple sclerosis, or stroke can impair sexual function.
Chronic Pain Conditions – Arthritis and fibromyalgia can make sexual activity uncomfortable.
Depression and Anxiety – Mental health issues can lower libido and increase performance anxiety.
Medications – Antihypertensives, antidepressants, and sedatives may have sexual side effects.

Nutritional Factors:
- Micronutrient Deficiencies – Lack of vitamins (A, C, D, E) and minerals (zinc, selenium) weakens immunity.
- Malnutrition – Protein deficiencies impair antibody production and wound healing.
- Obesity – Chronic inflammation from excess weight negatively impacts immune response.
Psychological Factors:
- Chronic Stress – Increases cortisol levels, which suppress immune function.
- Depression and Loneliness – Linked to higher inflammation and lower immune resilience.
- Cognitive Decline – Poor mental health affects self-care and immune health.
Drugs:
- Immunosuppressants – Used for autoimmune diseases but reduce infection resistance.
- Corticosteroids – Long-term use weakens immune response.
- Chemotherapy and Radiation – Destroys immune cells along with cancer cells.
Complementary and Alternative Medications (CAM):
- Herbal Supplements – Some, like echinacea and ginseng, may enhance immunity, while others (e.g., St. John’s Wort) interact with medications.
- Probiotics – Support gut health and immune function.
- Essential Oils and Homeopathy – Limited scientific support, but some may reduce stress and
