What is the reason for the strong odor in the elderly

The strong odor in the elderly may be related to factors such as slowed skin metabolism, sebum oxidation, chronic diseases, poor oral hygiene, and deterioration of urinary system function. Due to physiological decline, the secretion of sweat and sebaceous glands decreases in elderly people, and the accumulation of metabolic products can easily produce special odors through bacterial decomposition.

1. Slowdown of skin metabolism

Elderly people's skin's stratum corneum renewal rate decreases, and dead skin cells accumulate on the surface, which can easily breed bacteria when mixed with sebum. Microorganisms such as Staphylococcus on the surface of the skin break down fatty acids in sebum, producing volatile substances such as nonanal and octanal, forming a unique and stale body odor. It is recommended to choose a mild acidic shower gel for cleaning and avoid excessive use of alkaline soap.

2. Sebaceous Oxidation

The oil secreted by sebaceous glands undergoes oxidative reactions when exposed to air, producing unsaturated aldehydes. As age increases, the antioxidant substances in sebum decrease and the oxidation process accelerates. This type of oxidation product has a more pronounced odor when mixed with sweat. Proper supplementation of vitamin E and vitamin C can help delay sebum oxidation.

3. Chronic diseases

diabetes, liver and kidney diseases and other chronic diseases will lead to metabolic waste excretion obstacles. Ketone accumulation in the body of diabetes patients will emit rotten apple smell through breathing and sweat, and urea excretion through the skin of patients with renal insufficiency will produce urine odor. This type of pathological odor requires targeted treatment and management for the primary disease.

4. Poor oral hygiene

Periodontal diseases, dental caries, or improper denture cleaning can lead to the proliferation of oral bacteria, which decompose food residues and produce sulfides. Older people have reduced saliva secretion, weakened oral self-cleaning ability, and are more prone to oral odor. Daily use of dental floss to clean the gaps between teeth and regular professional cleaning can effectively improve the condition.

5. Degeneration of urinary system

Prostatic hyperplasia in elderly men is easy to cause urinary retention, female pelvic floor muscle relaxation may cause urinary incontinence, and residual urine will be decomposed by bacteria to produce ammonia odor. Frequent nocturia caused by decreased bladder function can also increase the probability of odor production. It is important to keep the perineum dry and clean, and replace the absorbent pads in a timely manner. Improving the odor of the elderly requires daily care, such as washing the wrinkled areas of the skin with warm water and choosing breathable cotton clothing. Pay attention to reducing the intake of sulfur-containing foods such as garlic and onions in diet, and supplementing zinc in moderation can help reduce sebum secretion. Regular health check ups should be conducted to control basic indicators such as blood sugar and blood pressure. Maintaining indoor ventilation and using air purifiers can also help reduce the concentration of odors in the environment. If the odor suddenly worsens or is accompanied by other symptoms, it is recommended to seek medical attention promptly to investigate potential illnesses.
