- Grave's disease is classified as an autoimmune disorder. In autoimmune diseases, the body's immune system mistakenly attacks its own cells.

2. **Identifying Key Characteristics**:
- The disease is characterized by hypersecretion of thyroid hormones, leading to various symptoms.

3. **Common Symptoms of Grave's Disease**:
- **Heat Sensitivity**: Individuals with Grave's disease often experience increased sensitivity to heat.
- **Weight Loss**: Despite an increased appetite, individuals typically lose weight due to increased metabolism.
- **Exophthalmos**: This refers to the bulging of the eyes, which occurs due to fat deposition around the eyes.
- **Enlarged Thyroid Gland**: The thyroid gland becomes enlarged, a condition known as goiter.
- **Anxiety**: Patients may also experience heightened anxiety levels.

4. **Analyzing the Options**:
- The question asks for the characteristic that is **not** associated with Grave's disease.
- The symptoms listed above (heat sensitivity, weight loss, bulging eyes, enlarged thyroid, and anxiety) are all true for Grave's disease.
- The only symptom that does not fit is **weight gain**, as individuals with Grave's disease typically experience weight loss.

5. **Conclusion**:
- Therefore, the correct answer to the question is that Grave's disease is characterized by all the symptoms mentioned except for weight gain.

**Final Answer**: Weight gain is not a characteristic of Grave's disease.
