Hypertension is a common medical condition that often has severe consequences over the long-term. You generally would not know that you have hypertension unless you have your blood pressure checked. If you have mildly elevated levels, lifestyle adjustments may be enough to lower your blood pressure within ideal ranges. If you need medication, you may need to have some adjustments to get your dose just right, especially early on. Blood pressure management is generally effective, and most people are able to avoid the complications of hypertension with lifestyle modifications and medical management.
Metabolic syndrome (also known as metabolic syndrome X) is a grouping of cardiac risk factors that result from insulin resistance (when the body's tissues do not respond normally to insulin). A person with metabolic syndrome has a greatly increased risk of developing type 2 diabetes, cardiovascular disease and premature death. In fact, another name for metabolic syndrome is pre-diabetes.
The undiagnosed/untreated metabolic condition that spreads. Metabolism is an intricate system of organs communicating with one another to do a job. If you have a problem in one area, it will affect other areas as well. The example I use with patients is to picture metabolism as an orchestra playing a song. If the flutes are playing off key or out of time, the other instruments in the band will likely wander off key and timing as well. In the end, everyone is off and the song is a mess. This is how metabolic damage can develop as well. An untreated thyroid condition will negatively affect all other systems and metabolism as a whole.
