Further symptoms of low gastric activity are:
In the muscle tissues: All muscles, including the crucial heart muscle and those of the intestine, require a healthy supply of B vitamins. This supply is missing in hypochlorhydria causing muscular weakness. 
Muscular wasting. Amino acids are not properly assimilated because of progressively poor digestion of protein. As a result we lose nitrogen which is essential for the production of strong lean muscles.  Cramps and spasms are caused by deficiencies of calcium, magnesium, iron, essential fatty acids, hypothyroidism and electrolyte imbalances, all these can be caused by low gastric activity. [1,3]
Slow healing of injuries and surgeries. Copper works in balance with zinc and vitamin C to form elastin, an important component of all muscle fibers. Zinc, copper and vitamin C are needed for healing, but all three are low or missing with low stomach acid. [12,15]
Paralysis or convulsions are caused by hypochlorhydria's electrolyte and hormone deficiencies and imbalances. Muscle and nerve tissues (in fact all cells) must be bathed in fluids which contain regulated amounts of electrolytes. (Calcium ions stimulate muscles and nerves, whereas potassium, magnesium and sodium relax them.) Hormones are critical in governing this process. 
Myasthenia Gravis.  Recovery from this disease has occurred many times when the diet and digestion are adequate. An adequate supply of B vitamins, vitamin E, amino acids and the electrolytes manganese and potassium (missing in hypochlorhydria) are needed.  (See Dysbiosis and Infections)
Chronic muscle pain from cellular deficiencies and imbalances  and from leaky gut syndrome/intestinal permeability.  (See Bowel)
In the Connective Tissue: The plasma that nourishes our cells is progressively lacking in oxygenating alkalizing electrolytes.  Metabolic acidic wastes accumulate and are stored in the collagen or connective tissue, resulting in severe inflammation and even cell death.  The connective tissue's repair system is slowed by poor circulation and impaired by a poor supply of the necessary nutrients, for example, the amino sugars (glycoproteins and glycosaminoglycans) L Proline, L Lysine and vitamin C. Copper is necessary to produce SOD, the innate antioxidant for joint health. (SOD removes free radicals three to ten times faster than vitamin C.)  The synthesis of collagen requires copper,  and copper, like the aforementioned nutrients, is not absorbed without sufficient HCl. The following symptoms and diseases show the long-term effects of mineral imbalances and unrestrained free radical damage.  Bursitis,  Tendinitis, Bunions (from calcium deposits),  Lupus erythematosis, Sjogren's syndro me, arthritis and rheumatoid arthritis.  Intestinal permeability (leaky gut syndrome) and a deficiency of the essential amino acid histidine are implicated in rheumatoid arthritis. (See Small Intestine and Dysbiosis)
Histidine deficiency: a low supply of HCl doesn't provide the enzyme activity needed to break down protein into amino acids [1,2] nor the coenzymes B3 and B6 needed to transform histidine into histamine, an important immune system chemical. The secretion of histamine by the mast cells of the stomach's connective tissue drives or stimulates the production of stomach acid. In...
