These medications can contribute to bone loss and can increase risk for osteoporotic fractures. Genetic
Maternal body build, lifestyle, and vitamin D status are some of the genetic and epigenetic effects that have been found to affect the BMD, specifically the developmental plasticity.Additionally, other studies have found that race (e.g. Black women have the lowest risk), age (i.e. older age), body mass (i.e. lower weight), and gender (female) play a role in contributing to the risk of osteoporosis. Although the incidence of developing osteoporosis and hip fractures vary between population groups, older age is consistently associated with a higher incidence of fractures due to osteoporosis. Social and nutritional factors
There are several environmental and social factors that can contribute to the risk of developing osteoporosis. Smoking tobacco can increase the risk by decreasing the ability of the intestine to absorb calcium. Caffeine intake and heavy alcohol were also correlated with the decrease in bone density in the elderly population.Without proper intake of vitamin D and calcium, it can increase the risk of osteoporosis in the elderly. These vitamin deficiencies pose as a risk factor, as it can decrease bone mass, decrease calcium absorption, and increase in bone turnover. There are also various medications can that interfere with the absorption of calcium, such as anticonvulsants, diuretics, corticosteroids, immunosuppressive medications, some antibiotics, and NSAIDS.
Other tests which can aid in the diagnosis of GSID but which are not truly diagnostic for the disease are the sucrose breath test, and a genetic test which tests for the absence of certain genes which are thought to be responsible for GSID.Sucrose (also called saccharose) is a disaccharide and is a two-sugar chain composed of glucose and fructose which are bonded together. A more familiar name is table, beet, or cane sugar. It was believed that most cases of sucrose intolerance were due to an autosomal recessive, genetic, metabolic disease. Based on new data patients with heterozygous and compound heterozygous genotypes can have symptom presentation as well. GSID involves deficiency in the enzyme sucrase-isomaltase, which breaks the bond between the glucose and fructose molecules. When disaccharides are consumed, they must be broken down into monosaccharides by enzymes in the intestines before they can be absorbed. Monosaccharides, or single sugar units, are absorbed directly into the blood.A deficiency of sucrase may result in malabsorption of sugar, which can lead to potentially serious symptoms. Since sucrase-isomaltase is involved in the digestion of starches, some GSID patients may not be able to absorb starches as well. It is important for those with sucrose intolerance to minimize sucrose consumption as much as possible. Dietary supplements or medications may be taken as a substitute for the missing enzyme or to introduce healthy bacteria into the immune system. Diagnosis
Chronic gastrointestinal symptoms that are fairly common but difficult to diagnose may be caused by congenital sucrase-isomaltase deficiency (CSID).
