But beneath this great wealth and prosperity, America seethed. Whenever you have two people—or peoples—joined in politics but doing diametrically opposing things, it is almost inevitable that at some point tensions and jealousies will break out. In the industrial North, there was a low, festering resentment that eight of the first 11 . presidents were Southerners—and most of them Virginians at that. For their part, the agrarian Southerners harbored lingering umbrage over the internal improvements policy propagated by the national government, which sought to expand and develop roads, harbors, canals, etc., but which the Southerners felt was disproportionately weighted toward Northern interests. These were the first pangs of sectional dissension.
Chronic low blood pressure with no symptoms is almost never serious. But health problems can occur when blood pressure drops suddenly and the brain is deprived of an adequate blood supply. This can lead to dizziness or lightheadedness. Sudden drops in blood pressure most commonly occur in someone who's rising from a lying down or sitting position to standing. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time. This is called neurally mediated hypotension. When it leads to passing out, if is called vasovagal syncope.
Fat malabsorption: Malabsorption of fat is the inability to digest or absorb fat. Fat malabsorption may occur because of reduced pancreatic secretions that are necessary for normal digestion of fat (for example, due to pancreatitis or pancreatic cancer ) or by diseases of the lining of the small intestine that prevent the absorption of digested fat (for example, celiac disease ). Undigested fat enters the last part of the small intestine and colon where bacteria turn it into substances (chemicals) that cause water to be secreted by the small intestine and colon. Passage through the small intestine and colon also may be more rapid when there is malabsorption of fat.
