Swelling around eyes and large popping eye balls are observed in an individual who has

Options

A. Less secretion of thyroxine in adult
B. Excessive secretion of thyroxine
C. Excessive secretion of calcitonin
D. Less secretion of thyroxine right from birth.

Answer

**Step-by-Step Solution:**

1. **Identify Symptoms**: The question describes symptoms of swelling around the eyes and large popping eyeballs. These symptoms are indicative of a specific medical condition.

2. **Recognize the Condition**: The symptoms mentioned are characteristic of Graves' disease, which is an autoimmune disorder that leads to hyperthyroidism.

3. **Understand Hyperthyroidism**: In Graves' disease, there is excessive secretion of thyroxine (T4) from the thyroid gland. This overproduction of thyroid hormones can lead to various symptoms, including exophthalmos (popping eyeballs) and swelling around the eyes due to fat deposition.

4. **Explain Exophthalmos**: The swelling and protrusion of the eyeballs (exophthalmos) occur because of the accumulation of fat and inflammation behind the eyes, which can also lead to complications such as difficulty blinking and potential eye infections.

5. **Evaluate Other Options**:
- Less secretion of thyroxine in adults would lead to hypothyroidism, which does not match the symptoms.
- Excessive secretion of calcitonin is associated with thyroid cancer, which is not relevant to the symptoms described.
- Less secretion of thyroxine from birth leads to developmental issues, not the symptoms in the question.

6. **Conclusion**: Based on the analysis, the correct answer is that the individual has excessive secretion of thyroxine (hyperthyroidism), which corresponds to Graves' disease.

**Final Answer**: The individual has excessive secretion of thyroxine (option B).
