Answer

To determine which of the following is not a symptom of hypothyroidism, we can analyze the common symptoms associated with this condition.

1. **Understanding Hypothyroidism**: Hypothyroidism is a condition caused by a deficiency of thyroid hormones. The thyroid gland, located in the neck, produces hormones that regulate metabolism, energy levels, and overall bodily functions.

2. **Common Symptoms of Hypothyroidism**:
- **Oedema**: This refers to swelling caused by excess fluid trapped in the body's tissues. It is a common symptom of hypothyroidism, often leading to changes in skin coloration.
- **Lethargy**: This is characterized by a lack of energy and motivation, which is also a significant symptom of hypothyroidism. Patients often feel tired and weak.
- **Mental Retardation**: In severe cases, particularly in children, hypothyroidism can lead to developmental delays and cognitive impairments.
- **Rise in Blood Urea**: This is not a symptom of hypothyroidism. An increase in blood urea levels is typically associated with kidney dysfunction or renal disease, not thyroid hormone deficiency.

3. **Conclusion**: Among the options provided, the rise in blood urea is not a symptom of hypothyroidism. Therefore, this is the correct answer.

**Final Answer**: The rise in blood urea is not a symptom of hypothyroidism.
