HMB, which stands for beta-Hydroxy beta-methylbutyric acid develops naturally within the body when a person consumes food which contains the essential amino acid called leucine. This latter substance is a feature of a number of popular and widely available foods including beef and fish, and when it enters the body, hmb is produced as a part of the metabolic process. HMB has since gone on to be developed and marketed on its own as a supplemental aid to nutrition, and in this format it is usually sold as a calcium salt and used primarily by those seeking to improve the ability of their body in endurance sports, you can find this supplement at Maximuscle.com.
It was Dr Steven Nissen of Iowa State University who initially discovered HMB in pigs and, following this initial discovery HMB was subjected to an extended period of research and trials, involving both human and animal studies, to determine whether the health benefits that had initially been noted were consistent and also whether there were any adverse side-effects to HMB usage. The benefits to health and wellbeing that HMB can help to provide include an improvement in the strength and weight of muscles, coupled with reduction in muscle wastage and loss of fat. This makes it very useful for those looking to prepare their bodies for sporting competitions which require endurance – such as cycling and long distance running.
However health benefits from HMB have also been noted for patients suffering from a number of different conditions and diseases. The muscle enhancements that HMB can help with are also very useful for patients suffering from diseases which cause muscle wastage – for example AIDS, HIV and some forms of cancer. Furthermore HMB has also had positive results when used on critically ill patients with chronic obstructive pulmonary disease as well as those who have suffered serious injuries as a result of extreme physical trauma.
Millions of women become pregnant every year and a significant proportion of these pregnancies are complicated by one or more of the medical disorders that can occur during pregnancy. Some of the medical disorders during pregnancy are common and some are less common and some of the medical disorders during pregnancy are rare. The pattern of medical disorders during is also changing. Medical science is advancing rapidly and many medical disorders which were considered contraindications of pregnancy few decades ago are no more considered contraindication of pregnancy. Due to advancement of obstetrics, neonatology, obstetric anesthesiology, and medicine, the expectation of happy outcome of pregnancy for the mother as well as the fetus has also increased to a great extent.
Marked physiological changes occur during pregnancy (e.g. marked increase in cardiac output and workload of heart, which is as much as 40% increase) and the mother’s body need to adapt to these physiological changes appropriately to have a good outcome of pregnancy. Medical disorders which interfere with physiological adaptations of pregnancy can increase the risk of a poor outcome of pregnancy and pregnancy may sometimes aggravate the preexisting medical disorder in a woman.
The medical disorders which can occur during pregnancy are preeclampsia (development of hypertension and presence of protein in urine after 20 weeks of pregnancy or gestation) which occurs in approximately 5-7% of all pregnancies, eclampsia, gestational hypertension, aggravation of existing essential hypertension, cardiovascular disorders (like mitral stenosis, mitral and aortic regurgitation etc.), renal disorders, pulmonary hypertension, pulmonary embolism, deep vein thrombosis, hormonal disorders (like diabetes, gestational diabetes, hypothyroidism or hyperthyroidism), blood disorders, neurological disorders, gastrointestinal disorders and liver diseases. The pregnant women are also prone to develop certain bacterial (urinary tract infection, which is very common medical problem during pregnancy) and viral infections (cytomegalovirus infection, rubella, herpes, HIV infection etc.).
