 Unexplored Liver disease a potential Killer

In 21 st century the globally most liver illness is from “ Fatty Liver “ . The world has competitively becoming technocratic with net result of explosive obesity, particularly in US ,over 60 million people are obese . Traditionally obesity related illness ; high blood pressure , Diabetes Type II , Heart disease , lung disease from Sleep Apnea , fat burden in arteries causing Stroke , Degenerative joint needing early replacement all were explored over few decades.
Liver fat from the early childhood till young adults was not known for long time. Recent two decades its overwhelming alertness brought attention most of the end stage liver illness ( cirrhosis ) also liver cancer from Fatty liver in next tweety years.
Obesity is the hallmark . Genetic , Demographic , Diabetes , Alcohol , other hormonal dysfunction such as Leptin and Adiponectin ; Steroid, estrogen , medications . The most important scenario is lack of exercise that keeps energy expenditure over calories excess causing silent culprit Insulin inactivity rather Overflow collectively named insulin resistance interfering appropriate sugar handling in tissue causing excess fat in body stores like Abdomen . In liver free fatty acids from digested sugar have poor shuttle to the cell batteries called mitochondria for fat digestion and low or inactivity of enzymes to mobilize free fat named glycerols :mono, Di,and triglyceride , called oxidative dysfunction or lipid per oxidation formation of free radicals and toxic radicals those un digested fats remain stuffed in the liver cells making microvascular and macro-vascular fat called Steatosis and ballooning liver . The liver suffer from respiratory flow and stress called oxidative stress so liver spills enzymes in inflammatory response . 
On going inflammation will destroy liver cells that brings the repair process with hard tissue fibrous in origin replacing liver tissue in decade . As liver is regenerative organ will grow neoformation giving lumpy bumpy look called cirrhosis . Every year it further decompensated and dysfunctional causing ; Jaundice . Free fluid in the and abdomen Fail to remove toxins goes to brain causing mental fog and comma . Kidneys suffer from filtration and brick like liver does not permit blood flow through liver so veins full of blood go through other avenue and makes stomach and food pipe full of engorged called varicose vessel .ruptured vessel is ominous .
Clinical symptoms are rarely apparent ; enlarged liver , moderate rise of liver enzymes which is the most common cause in the world .
Diagnosis : clinical suspicion . Exclusion of other causes of abnormal liver function . Blood test for Insulin resistance , high lips, glucose , other blood test for fibrosis called FIB 4, APRI , and NASH score , Radiological Ultra sound .now very sophisticated MRE and special scan for measurement of fiber.
Treatment : The only treatment is slow weight loss ,cardiology monitoring is judicious before vigorous exercise plan . Diet low calorie high protein and less fat . In Morbid obesity Gastric Bypass in experience hands in good centers are optimal choice.
Coffee three cups and anti Oxidant Vitamins E , probiotics . In Few years many drugs are evolving to cure fatty liver . In liver failure liver transplantation is the only remedy . Post Transplant Fatty liver is common in five to ten years .
In conclusion : Fatty liver is ominous . It is global and huge pandemic threat . Most liver transplantation in two decades will be from Fatty liver . Fatty liver escalates a huge social economic burden unless addressed early and stoppage of the malady . CDC and American liver Foundation ,American society of liver disease have definitive guidance for Fatty liver and management .

No more ointments, creams or suppositories. With onset occurring after the age of 30, hemorrhoids affect more than half the population at some point in their lives.

Unlike other techniques that use a metal clamp to grasp the hemorrhoid during banding, we use a smaller, gentler, single use and disposable suction device to minimize discomfort and complications.

The CRH O'Regan System is a simple painless and highly effective procedure (99.1%) that can be preformed in less than a minute. How simple?  Dr Mastali will place a tiny rubber band around the internal hemorrhoid to cut of its bloody supply. The hemorrhoid then shrinks and falls off within a day or so, usually without you noticing and that's it. Once the hemorrhoid is gone, so are your symptoms. The CRH O'Regan System is the only hemorrhoid removal treatment that requires no pain medication and virtually no recovery time. In fact, many of our patients with office jobs return to work following the appointment. Other rest at                                                                                                                             home afterwards and resume normal activities the next day.

                               Hemorrhoid Classification:

           Grade 1- Hemorrhoid bleeds but doesn't prolapse outside of the anal canal

           Grade 2- Prolapses, usually with defecation, but retracts spontaneously

           Grade 3- Requires manual reduction into the anal canal after prolapsing

           Grade 4 Prolapsing tissue cannot be manually replaced and may be strangulated or thrombosed.
