More Info

---

Frequent dizziness in seniors can be a concerning symptom, especially when it leads to significant discomfort or limits daily activities. Understanding the potential causes and implications of dizziness is crucial for proper management and care.

Dizziness can manifest in various forms, including lightheadedness, vertigo (a spinning sensation), or a feeling of unsteadiness. For seniors, the causes of dizziness can be multifactorial, often involving a combination of medical conditions, medications, and environmental factors.

1. Common Causes of Dizziness in Seniors:
- Vestibular Disorders: Conditions affecting the inner ear, such as benign paroxysmal positional vertigo (BPPV) or vestibular neuritis, can lead to episodes of dizziness or vertigo.

- Orthostatic Hypotension: This condition occurs when a person experiences a drop in blood pressure upon standing, leading to lightheadedness or fainting. It is particularly common in older adults and can be exacerbated by dehydration or certain medications.

- Medication Side Effects: Many medications can cause dizziness as a side effect. This includes blood pressure medications, sedatives, and even herbal supplements like ginkgo biloba (銀杏), which your mother is taking. Ginkgo biloba can affect blood flow and may lead to dizziness in some individuals.

- Neurological Conditions: Conditions such as Parkinson's disease, multiple sclerosis, or even transient ischemic attacks (mini-strokes) can present with dizziness.

- Cardiovascular Issues: Heart problems, including arrhythmias or heart failure, can lead to inadequate blood flow to the brain, resulting in dizziness.

- Dehydration and Nutritional Deficiencies: Seniors are at higher risk for dehydration, especially during illness. Additionally, deficiencies in vitamins such as B12 or folate can contribute to dizziness.

2. When to Seek Medical Attention:
- If your mother experiences frequent or severe dizziness, especially if it is accompanied by other symptoms such as headache, vision changes, weakness, or difficulty speaking, it is essential to seek medical attention promptly. These could be signs of a more serious underlying condition.

- A thorough evaluation by a healthcare provider is necessary to determine the cause of her dizziness. This may include a physical examination, blood tests, and possibly imaging studies or referrals to specialists such as a neurologist or an ear, nose, and throat (ENT) doctor.

3. Management and Prevention:
- Medication Review: It is crucial to review all medications, including over-the-counter drugs and supplements, with a healthcare provider to identify any potential side effects or interactions that may be contributing to dizziness.

- Hydration and Nutrition: Ensuring adequate fluid intake and a balanced diet can help prevent dizziness related to dehydration or nutritional deficiencies.

- Balance and Strength Training: Engaging in exercises that improve balance and strength can help reduce the risk of falls and improve stability.

- Environmental Modifications: Making changes at home, such as ensuring good lighting and removing tripping hazards, can help prevent falls associated with dizziness.

In conclusion, frequent dizziness in seniors can arise from various causes, and it is essential to approach this symptom with a comprehensive evaluation. Given your mother's situation, it would be advisable to consult her healthcare provider to discuss her symptoms, review her medications (including ginkgo biloba), and explore further diagnostic options. Early intervention can significantly improve her quality of life and reduce the risk of complications associated with dizziness.
