You might not notice any symptoms of hyperparathyroidism, but it can cause symptoms as it worsens. If you have symptoms, it's important that you get a proper diagnosis immediately so you can begin treating your condition. Otherwise, your symptoms may continue to worsen. Visit your doctor if you experience the following symptoms: Fragile bones Bone and joint pain Abdominal pain Excess urine Kidney stones Getting easily fatigued Depression Forgetfulness Nausea or vomiting Feeling ill with no cause The best way to treat your high pth levels is to treat your underlying condition. Your doctor can help you develop a treatment plan that meets your needs. For a mild case, natural treatments may help. However, it's possible that your doctor will recommend additional treatments, like medication or surgery, if your symptoms are severe. Follow your doctor's advice and see them regularly so they can monitor your progress.Your doctor will test your pth levels often to make sure you're improving. High PTH levels can develop when your body isn't getting enough calcium or vitamin D. However, too much vitamin D can become harmful, so you shouldn't take a supplement unless you know your levels are low. Ask your doctor for a simple, painless blood test to check if you have a vitamin D deficiency. Often this condition develops because you're having trouble absorbing these vitamins from your diet, which likely means you're having digestive issues. In that case, you'll likely need to treat the underlying cause first. In other cases, your high PTH levels are caused by another issue, which results in overproduction of PTH and therefore, causes your calcium levels to be TOO high instead. Some medications can increase your calcium levels, which can be bad when your PTH levels are high. Diuretics and lithium can be culprits, so ask your doctor if any of your medications could be causing an issue. Don't forget to discuss any natural remedies you're taking, too. For instance, thiazide diuretic can be an issue.

summary: See your doctor if you have hyperparathyroidism symptoms. Work with your doctor to treat the underlying cause. Get your vitamin D levels tested before taking a supplement. Discuss your medications to make sure they're safe.
