I have been feeling very sick. My PTH intact level is 134.4 pg/ml and my calcium is 11 mg/ld. Also I have blurry vision and just feel really sick.

Thanks for writing in. I’m not surprised that you are feeling badly. Your calcium and PTH indicate primary hyperparathyroidism, and most people with this will develop symptoms. The most common symptoms are often non-specific, things like fatigue, insomnia, and brain fog. People also report that they just don’t feel like themselves anymore. They feel generally unwell, though it might be hard to pin down exactly what is wrong. Your blurry vision can be a result of parathyroid disease as well. Calcium is important throughout the body, so we see a lot of seemingly unrelated symptoms all happening because of parathyroid disease - such as heartburn, bone pain, headaches, blurred vision, kidney stones, and many others.

The only cure for primary hyperparathyroidism is an operation to remove the diseased parathyroid gland or glands. Fortunately, most people notice significant improvements in their symptoms in the weeks following parathyroid surgery. This is a good time to seek out a parathyroid specialist and work toward getting cured.
