Hypercalcemia
One cause of ulcers can be hypercalcemia, which means over-production of calcium. When one has hypercalcemia, the blood contains an above-normal calcium level.
Long-term hypercalcemia tends to increase the production of gastrin, which can lead to peptic ulcers. It can even contribute to soft tissue pancreatitis. If the calcium level of your blood is greater than about 15 mg/dL, it is considered a medical emergency that should be aggressively treated.
