Medical Terms Difference

Helpful, thanks more  

DEAR ROOPSINGH, THESE TERMINOLOGY IS USED IN MEDICAL TERMS,SOME PPL USES IN LAY MAN WORLD TO EXPRESS THE ABOVE TERMS IN THEIR WORDS...... IT SEEMS U HAVE COME ACROSS THESE TERMS MAY BE DUE TO HOSPITALIZATION,OR U CAME ACROSS ANY MEDICAL CASE...NO ISSUE.... JUST MAKING SIMPLE FOR U IN UNDERSTANDING THIS TERM..... LETS TAKE::ACIDITY---ACID REFLUX------GERD....... 1-GERD::GASTROESOPHAGEAL REFLUX DISEASE.---ACIDITY AND ACID REFLUX R IN ALL SAME TERMINOLOGY...USED IN DIFFERENT WAY BY DR AND LAY MAN...... ACID REFLUX IS SYMPTOM,ACIDITY IS USED BY LAY MAN TO EXPRESS.... GERD IS DISEASE ASSOCIATED WITH OTHER SYMPTOM TOO. NOW MEANING R SIMPLE::::: STOMACH RELEASES HCL FOR DIGESTION OF FOOD,THAT ACID WHEN MOVES IN OPPOSITE DIRECTION FROM STOMACH ENTERS IN ESOPHAGUS...THAT FEELING HAS ACIDITY,SINCE IT IS REFLUX FROM STOMACH SO SAID ACID REFLUX..AND IF ASSOCIATED WITH OTHER SYMPTOM WOULD BE SAID AS GERD.. 2-METABOLIC ACIDOSIS::IS COMPLETE DIFFERENT TERM ,NOT RELATED COMPLETELY WITH ABOVE STOMACH TERM.BLOOD HAS PH..7,DURING INVESTIGATION WITH ARTERIAL BLOOD GAS TESTING IS DONE,ACCORDING TO SYMPTOMS DURING HOSPITALIZATION SEEN. :WITH LESSER PH IS CALLED ACIDOSIS,AND LARGER PH IS CALLED AS ALKALOSIS. JUST EXPRESSED IN SIMPLE TERMS DONT NEED TO GO DEEPER INTO IT,SINCE THERE R MANY MECHANISMS OF BODY PLAY ROLE IN IT.......... -----SO MAY BE U HAD GOT CONFUSED WITH TERM ACID AND SO TRIED TO UNDERSTAND ABT WORD ACID.....ITS A MEDICAL TERMINOLOGY USED IN DIFFERENT ASPECTS....... IF U HAVE COME ACROSS ANY CASE U CAN EXPRESS HERE............. more

metabolic acidosis is altogether a different terminology vis a vis other terms you mentioned , acid reflux or reflux esophagitis or achlasia cardia is also known as gerd or gastro esophageal reflux disease or disorders, it has to do with reduction of tone of esophageal sphincter(muscular guard at the junction of stomach n food pipe)which prevents leaking of food back to food pipe from stomach, it shows mild to severe episodes of pain or burning in the central chest or may simulate pain found in IHD/CAD(heart diseases) ie angina pectoris , or this pain may radiate to back of chest where it may be mistaken for skeletal pain /or vertebral spondylosis , but most of this come after few minutes to 1 hour after having eaten, sometimes continuous leaking of food may result into corrosion of food pipe resulting into chest discomfort , an advance condition called barretts esophagus may crop up from chronic esophagitis(inflammation of esophagus or food pipe), acid peptic disease or acid dyspepsia may be consequent upon longstanding GERD or it may be simultaneously occuring disorder, long term acidity resulting from loss of stomach buffering mechanism , lowering of ph of the stomach milieu, disturbance in prostaglandin mechanism, all or one of them may make lining of stomach more vulnerable to strong acidic environment present causing gastritis , this may range from mild gastritis , gastric erosion to full fledged gastric ulcer s. taking excessive pain killers (more or so cox 1 inhibitors like bruffen,aspirin pcm etc) may also induce such lesions. whereas metabolic acidosis means there is lowering of ph in blood and tissues , acedemia means lowering of PH in blood,mostly blood is maintained at 7.4 , if this goes below 7.1 there are higher chances of patients death ,cardiac arrhythmmia ,hypotension and in long term rhabdomyolysis(dissolution of muscles ) , acidosis means blood and tissue buffering is either hampered or overhelmed due to production of H+ (apart from k+/na+),normally there are 2 main anions or negative ions in body it is hco3-(carbonates) or cl-(chloride), metabolic acidosis may occur in renal tubular necrosis,long term kidney failure ,diarrhoea and vomiting etc ketoacidosis (one type of acidosis)of of type diabetes is very common cause of manageable emergency in setting of DM(diabetes mellitus).lactic acidosis is also one of the common causes predisposing to metabolic acidosis. hope this will be useful ,good luck more  

Metabolic acidosis in hyper acidity produced by the system when acid is not properly excreted by kidneys. Other forms of acidity you have mentioned are similar in nature but can damage the system in different ways causing ulcers, infections and also heart problem. Constant heart burning can be caused by defects in liver functioning or by intake of fatty food and alcohol with little or no exercise, thus resulting in accumulation of acid which can cause pain, nausea and sometimes, if not treated, ulcers.
