Why do I sometimes feel nauseous when I'm really hungry?

User Avatar

Asked by Rodrigo Schoen

I feel you—I get that a lot, too. There are two likely answers. One is that your stomach produces excess acid when you’ve been ignoring your hunger for a while, and that acid can splash up into your esophagus and cause nausea.

The other possibility is that you’re extra sensitive to ghrelin, the hormone our bodies make to alert us to our hunger. For some people, high levels of that hormone can make them slightly nauseous. If your nausea is severe, though, you should definitely talk to your doctor about it—it could be a sign of metabolic syndrome.

User Avatar

Asked by Wiki User

cholecystitis is inflammation of the gallbladder that develops over hours, usually because a gallstone obstructs the cystic duct.

Cholestasis?

User Avatar

Asked by Wiki User

Definition

Cholestasis is any condition in which the flow of bile from the liver is blocked.

Alternative Names

Intrahepatic cholestasis; Extrahepatic cholestasis

Causes, incidence, and risk factors

There are many causes of cholestasis.

Extrahepatic cholestasis occurs outside the liver. It can be caused by:

  • Bile duct tumors
  • Cysts
  • Narrowing of the bile duct (strictures)
  • Stones in the common bile duct
  • Pancreatitis
  • Pancreatic tumor or pseudocyst
  • Pressure on an organ due to a nearby mass or tumor
  • Primary sclerosing cholangitis

Intrahepatic cholestasis occurs inside the liver. It can be caused by:

  • Alcoholic liver disease
  • Amyloidosis
  • Bacterial abscess in the liver
  • Being fed through a vein (IV)
  • Lymphoma
  • Pregnancy
  • Primary biliary cirrhosis
  • Primary sclerosing cholangitis
  • Sarcoidosis
  • Serious infections that have spread through the bloodstream (sepsis)
  • Tuberculosis
  • Viral hepatitis

Certain medications can also cause cholestasis. See: Drug-induced cholestasis

Symptoms
  • Clay-colored or white stools
  • Dark urine
  • Inability to digest certain foods
  • Itching
  • Nausea or vomiting
  • Pain in the right upper part of the abdomen
  • Yellow skin or eyes
Signs and tests

Blood tests may show higher than normal levels of bilirubin and alkaline phosphatase.

Imaging tests are used to diagnose this condition. Tests include:

Treatment

The underlying cause of cholestasis must be treated.

Expectations (prognosis)

How well a person does depends on the disease causing the condition. Stones in the common bile duct usually can be removed, curing the cholestasis.

Stents can be placed to open areas of the common bile duct that are narrowed or blocked by cancers.

Complications
  • Diarrhea
  • Organ failure can occur if sepsis develops
  • Poor absorption of fat and fat-soluble vitamins
  • Severe itching
  • Weak bones (osteomalacia) and osteoporosis (due to very long-term cholestasis)
Calling your health care provider

Call your health care provider if you have:

  • Persistent itching
  • Yellow skin or eyes
  • Other symptoms of cholestasis
Prevention

Get vaccinated for hepatitis A and B if you are at risk. Avoid intravenous drug use and needle sharing.

Can you drink decaffeinated coffee with gastritis?

User Avatar

Asked by Wiki User

Generally, the issue with gastritis is the acid and oils in the coffee, not the caffeine.

Some of the ways to reduce the acids is to stick with light roasts in a drip maker. Don't use commercial creamers. They are mostly made of oils. A little bit of baking soda will neutralize the acid. It's a small amount, so go easy.

User Avatar

Asked by Wiki User

Gastrointestinal oncology is a broad term that refers to the treatment of several malignant conditions pertinent to digestive organs and the gastrointestinal tract.

The diseases Treatable with Gastrointestinal oncology include:

  • Esophageal Cancer
  • Gallbladder Cancer
  • Pancreatic Cancer
  • Bile Duct Cancer
  • Colorectal Cancer
  • Primary Liver Cancer
  • Gastrointestinal Carcinoid Tumors
  • Stomach (Gastric) Cancer

There are mainly four stages of stomach cancer which include:

  • Stage I: At stage one, the cancerous mass is only limited to the top layer of tissues lining the stomach or esophagus. The tumor may also spread to a few neighboring lymph nodes.
  • Stage II: At this stage, the cancer tumor spreads deeper and reaches to the stomach or esophagus’s muscle layer. Moreover, the cancer cells may also advance to more lymph nodes.
  • Stage III: At this stage, cancer cells grow to all layers of the stomach or esophagus. They may also reach extensively to lymph nodes and nearby organs.
  • Stage IV: This is an advanced stage where cancer has spread to all distant areas of the body.
