Potential Causes of Calcium Deficiency

  • Antibiotics may inhibit the body’s ability to absorb calcium.

  • Lack of Vitamin D

  • Kidney failure

  • Magnesium Deficiency

  • Alcoholism

  • Leukemia

  • Effects of Chemotherapy

  • Diuretics

  • Excessive Caffeine Consumption

  • Phosphates (from soft-drinks)

Hypocalcemia and Symptoms

Hypocalcemia is basically, low calcium or calcium deficiency. Hypocalcemia is determined through a blood test.

Symptoms Include:

  • Twitching muscles and nerves

  • Confusion

  • Irregular heartbeat

  • Numbness or Tingling in Extremities (fingers and toes)

Who is at increased risk? Patients with Crohn's disease need to be very aware of their various symptoms. In addition to other risks, Crohn's disease increases the risk of osteoporosis.

Similarly spelled terms related to calcium, potassium, sodium or magnesium.

  • Hypercalcemia: high levels of calcium.

  • Hypokalemia: low levels of potassium.

  • Hypotremia: low levels of sodium.

  • Hypomagnesemia: low levels of magnesium.

Calcium: Benefits and Deficiency Issues

Calcium: an essential mineral used by the body for the development and maintenance of strong bones and teeth. Close to 99% of calcium is located in our bones and teeth. In addition, calcium together with vitamin D is vital in the prevention and care of osteoporosis. However, calcium is not only used by the body for these areas, calcium is also important for the effective function of cardiovascular, muscular and nervous systems.

Osteoporosis: Studies have concluded calcium and vitamin D may help prevent postmenopausal bone loss and subsequent osteoporosis. Bone loss is also evident in older men and they may benefit from consuming vitamin D and calcium rich foods or supplements.

Hypoparathyroidism: Caused by an under-active parathyroid gland, patients are generally treated with a calcium rich diet, calcium supplements and a low phosphorus diet.

Premenstrual Syndrome (PMS): A diet rich in magnesium and calcium have shown improved symptoms of PMS. Studies have described a 50% reduction in headaches, bloating and even moodiness.

Cardiovascular Disease: Although further studies are needed, it was found a diet with added calcium decreased the absorption of lipids (fats) by the body. This in-turn produced lower cholesterol levels, and reduced the risk of ischemic heart disease. However, there have also been some concerns that the sudden stop of calcium supplementation may provoke adverse effects.

High Blood Pressure (Hypertension): Calcium, magnesium and potassium are vital to healthy cardiovascular function. All three are identified in assisting the body reduce high blood pressure. In one particular study, women who had three servings of low-fat dairy per day reduced their overall blood pressure readings.

High Cholesterol: A combination of calcium supplements, exercise and a healthy diet may improve dangerous cholesterol levels.

Stroke: Studies were able to confirm women who consumed calcium through diet and supplements significantly reduced their risk of having a stroke.

Weight Loss: A variety of studies have found those who consumed calcium and calcium supplements had better weight loss results than those who did not increase their intake.

Colon Cancer: Calcium supplements and diet may help reduce the risk of colon cancer.

A diet rich in potassium, magnesium and calcium have proven to have increased benefits against cardiovascular diseases and high blood pressure.

Dangers and Side Effects

Problems with Excessive Calcium Consumption: Just like most medications and nutrients, too much of a good thing may lead to other health issues and cause increased strain on the kidneys and liver.

Potential risks and conditions:

  • Kidney stones
  • Hypercalciuria: high levels of calcium in the urine.
  • Constipation
  • Inhibit absorptions of certain minerals or vitamins: zinc and iron.
  • Increase the risk of prostate cancer.

  • Meats
  • Poultry
  • Fish: sardines are a rich source of calcium.
  • Legumes
  • Eggs
  • Nuts
  • Kale
  • Broccoli
  • Spinach

      Tamara14, thank you for reading and commenting. I apologize for my late response. Your comment seemed to slip my radar. I hope your transition from Squidoo has been a positive one.

      Yes, Mg and Ca are a common topic for me as well. Regardless of what mineral, vitamin or antioxidant benefit I am analyzing they always seem to be actively involved.

      This was very informative, thank you. After reaching 40 we tend to think a bit more about our health I guess and Mg and Ca are two of my most researched topics recently. I've just came from Squidoo and learning my way around, so discovering great hubs like this is such a bonus. I am looking forward to getting back to your impressive list very soon.

      pinto2011, thank you so very much for your lovely comment, I greatly appreciate it.

      tillsontitan, how right you are, vitamin D is so vital. As I continue my research on natural food sources I am finding how combinations are truly vital in maintaining proper levels of nutrients. Not always an easy task though. It is nice to know there are a variety of supplements out there to help beef up whatever our diet may lack. I'm personally trying to keep my meals as 'colorful' as possible, more colors more nutrients. :) Thank you for your votes, comments and most importantly, your support.

      vibesites, I've personally tried giving up caffeine and have not been successful. I do need to monitor quantity though due to high blood pressure. Thank you for reading and commenting.

      I never thought caffeine is one of the culprits of low calcium. I'll take note of that. Thanks! :)

      kelleyward, yes, weight bearing exercise does improve bone and muscles health. We still need our calcium and vitamin D too. Fortunately there are many foods that contain multiple vitamins and minerals. Thank you for reading and commenting.

      old albion, I do hope you find relief for your kidney stones. Please take care of yourself. Glad to see you stopped by.

      susiebrown48, it sure does. Calcium can also affect blood pressure. It is definitely an important nutrient for maintaining optimum health.

      Diana Lee, low fat cheese, milk and yogurt has been found to reduce blood pressure. I included the study on my foods that reduce blood pressure hub. All it takes is three servings a day...pretty neat. Plus, you also get your calcium and vitamin D. Thanks for the votes.

      teaches12345, thank you so much! I greatly appreciate that. Glad you are enjoying the series. I'm learning quite a bit as I work my way through the different nutrients and benefits. Thanks for the votes.

      ChrustyWrites, isn't it amazing how much spinach has in it? Good stuff. Glad I like it. I'm also glad to see you have stopped by to read and comment.

      This is very interesting. Calcium is also good for people suffering from muscle spasms. I had to cut back on calcium supplements because of constipation, but low fat milk and yogurt are equally effective. Vote up.
