What can be the cause of weakened muscle and kidney functioning?
a. too little potassium
b. too much potassium
c. too little calcium
d. too much calcium

The presence of too much calcium can cause the muscles and kidney functions to weaken.

Further Explanation:

The condition in which the concentration of calcium in the blood becomes abnormally high is known as hypercalcemia. The parathyroid glands overreaction causes the condition. Certain medical disorders, too much vitamin D and calcium intake, cancer etc. are also the causes of hypercalcemia. Too much calcium can cause kidney stones, weakening of bones etc.

In bones, leaching of excess calcium in the blood from the bone occurs. The leaching leads to the weakening, pain and depression of the bones. In the muscles, the excess of calcium causes contraction of the muscles which eventually causes excess need of energy in form of ATP. The muscles weaken do to this condition. In the kidneys, excess of calcium can deposit in the parts of kidney causing kidney crystals over time, the crystals may combine to form kidney stones. Passing a stone can be extremely painful. The excess of calcium in the blood can also cause strain in the kidney due to the need of extra filtration. This condition causes frequent urination as well as excessive thirst. Severe hypercalcemia can limit the kidney’s ability to cleanse the blood and eliminate fluid.

Thus, the presence of too much calcium can cause the muscles and kidney functions to weaken.

    however, coronary heart disease , or chd, is actually a result of coronary artery disease, or cad, said edward a. fisher, m.d., ph.d., m.p.h., an american heart association volunteer who is the leon h. charney professor of cardiovascular medicine and also of the marc and ruti bell vascular biology and disease program at the nyu school of medicine.

  with coronary artery disease, plaque first grows within the walls of the coronary arteries until the blood flow to the heart’s muscle is limited. view an illustration of coronary arteries. this is also called ischemia. it may be chronic, narrowing of the coronary artery over time and limiting of the blood supply to part of the muscle. or it can be acute, resulting from a sudden rupture of a plaque and formation of a thrombus or blood clot.

    the traditional risk factors for coronary artery disease are high ldl cholesterol, low hdl cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to fisher. obesity may also be a risk factor.

    “coronary artery disease begins in childhood, so that by the teenage years, there is evidence that plaques that will stay with us for life are formed in most people,” said fisher, who is former editor of the american heart association journal, atvb. “preventive measures instituted early are thought to have greater lifetime benefits. healthy lifestyles will delay the progression of cad, and there is hope that cad can be regressed before it causes chd.”

  living a healthy lifestyle that incorporates good nutrition, weight management and getting plenty of physical activity can play a big role in avoiding cad.

    “coronary artery disease is preventable,” agreed johnny lee, m.d., president of new york heart associates, and an american heart association volunteer. “typical warning signs are chest pain, shortness of breath, palpitations and even fatigue.” if you feel any of these symptoms, don’t delay — call 9-1-1.
