Stomach Cancer Cause Symptom Treatment

-
Stomach cancer is also called as gastric cancer.

Stomach cancer is commonly occur in lining of stomach mucosal area. It start with inflammation and irritation of the mucosal lining. It further increase to form swelling and damage to normal gastric cell.

Most common causes of gastric or stomach cancer is bacterial infection such as helicobacter pylori. Other risk factors are smoking, pickled vegetables and obesity. It can also occur by genetically from any of family history.

Stomach cancer does not have any symptoms. In early stomach cancer, heartburn, indigestion, burning sensation occur in chest area. Abdominal discomfort, decreased food craving also seen in patients.

Cause


Stomach cancer commonly occur due to long term irritation to mucosal lining by either bacterial or through gastric irritant such as tea, coffe, red meat etc.

Stomach cancer develop when cells of gastric area start multiplying abnormally and rapidly.

Other causes and risk factors are,

  • Genetic 

It involve previous history of stomach cancer. It increase chance of reoccurance of cancer. 

  • High acid formation in stomach 

Excess production of acid formation damage and injured cells. Chronic irritation to gastric cell develop stomach cancer.

  • Metabolic error 

Metabolic error may cause retention of food particles and harmful enzyme in gastric area. It further causes infection ad inflmmation in abdomen causing stomach cancer.

  • Helicobacter infection 

Bacterial infection lead to form neoplasm (lymphoma) which further develops into stomach cancer. 

  • Intestinal polyps

Intestinal polyps is small vascular growth on surface of mucous membrane. It can develop into cancer.

  • Gastric irritants

Gatric irritants such as smoking, alcohol, eating junk food, red meat, excess tea or coffe irritate gstric area. 

  • Stomach ulcer 

Chronic ulcer causes death of stomach cell and also weaken mucosal membrane which can lead to stomach cancer.

  • Stomach surgery
Stomaxh surgery increases risk of stomach cancer. 

  • Chronic inflammation of stomach layer 
Chronic inflammation and irritation to stomach layer causes damage to gastric cells and lead to development of gastric cancer.

      Risk factors are :-

      • Injury to stomach

      Any external injury to stomach lining or traumatic injury to abdomen alter functions of gastric area.

      • History of stomach cancer

      Previous history of cancer increase chances of reoccurrence of stomach cancer.

      • Diet ex. meat, oily food

      Certain food such high cholesterol, oily food, high cooked meat or other substances are hard to digest. It lead to inflammation and irritation to gastric cells.

      • Less physically active & obesity 

      Person who is less physically active and obese has high cance of reoccurance of stomach cancer.

        Symptom


        Stomach cancer results in, 

        • Abdominal pain 

        Stomach cancer causes damage to cells and muscle of gastrica area. Nerve ending get stimulated by damage tissues & suppress cells due to swelling and inflammation which causes severe abdominal pain.

        • Bloating in abdomen 

        Stomach cancer causes person to bloating (presence of gas) in abdomen. 

        • Feeling of fullness 

        It occur due to inflammation, swelling and lymphoma formation in gastric area which make feeling of fullness to stomach.

        • Nausea and vomiting 

        Nausea and vomiting occur as a result if abnormal fluid formation in the body. 

        • Loss of appetite 

        Person has decreased craving for food 

        • GI bleed

        In severe stomach cancer, cells and tissues get ruptured and bleeding occur internally. It can also come out by voming or during defecation. 

        Other symptoms are 

        1. Vomitig with blood 
        2. Weight loss
        3. Fatigue 
        4. Heart pain 
        5. Bloody stool 
        6. Diarrhea or constipation 

        Diagnosis 


        Stomach cancer is diagnosed by various test explain below,

        • Complete blood count test

        Complete blood count test involve checking blood count, presence of infection and cancer cell in blood. It helps to diagnose cancer and infectin.

        • Imaging test 

        Imaging test involve X-ray and MRI which helps to visualize the affected area such as swollen area, cancer cell and spread of inflammation.

        • Gastroscopy

        In gastroscopy, a thin light tube is insert in the abdomen with camera attached to front to visualize cancer cells and stomach mucosal lining. It also used to remove mucosal secretion for lab test.


        • Fecal occult blood test

        Frcal occult blood test involve checking presence of blood in stool microscopically. It help to diagnose cancer.

        Treatment 


        Stomach cancer is manage by chemotherapy (drug therapy), radiation and surgical treatment.

        • Chemotherapy drug

        Chemotherapy is give on early period to decrease growth of bacteria and cancer cells. Commonly given medicines are carmustine, doxorubicin and ciplatin and taxotere.  

        • Surgical treatment 

        • Endoscopic mucosal resection (EMR) 

        In EMR, endoscope is insert into the abdomen and affected mucosal area is removed from the stomach area. It uses in early stomach cancer.

        • Partial Gastrectimy 

        In partial Gastrectomy, surgeon remove affected part of the stomach. It remove all the cancer cells from body. 

        • Total Gastrectomy 

        In total Gastrectomy, total stomach is removed from the body. 


        • Radiation therapy

        Radiation therapy involve passing a beam if light on tumor and cancer cells. This light break bond on cancer cell and kill them. It also help to break tumor in small sizes and kill cancer cells

        Diuretic Classification Use Side Effects

        -
        Diuretic drug Diuretic are define as drug causing loss of water and fluid from the body. It is typically use in swelling, edema and oliguria/decreased kidney output. Diuretics are classified based upon site of action and mechanism of action, there are four types of diuretics,  Osmotic diuretics  Thiazide diuretics  Loop diuretics  Potassium sparing diuretics  Osmotic diuretics  Osmotic diuretics increase amount of filtrable substance in body which increase filtration and urine production. Osmotic diuretics are filtered by glomerulus and further increase osmosis in nephron tube to carrying filtration process. Ex. Mannitol, sodium chloride is physiological diuretic Osmotic diuretics use in, Prophylaxis treatment of renal failure  It is used when kidney is not functioning properly. It help kidney to filter blood and inhibit oliguria. Head injury  In this, osmotic diuretics maintain water balance in the ...

        -
        Systole means contraction of heart muscles. It occurs after diastole relaxation of blood vessels. Similar word for systol is squeeze.  WHAT IS MEANING OF SYSTOLE? Systole is simply means contraction of heart. When blood is filled inside the atrium or ventricles, heart is contracted. When chambers got fully filled, pressure from the systole pushes blood to front in two places in lungs and in aorta. After this, heart enters in diastolic phase, relaxation phase.

        ACUTE RESPIRATORY DISTRESS SYNDROME

        -
        Acute respiratory distress syndrome is a spectrum of symptoms that arise due to severe respiratory dysfunction. It commonly occurs due to chronic infection in lung, muscle spasm, and secondary pulmonary diseases such as pneumonia, ARDS is characterized by severe breathing difficulty, respiratory failure, severe hypoxia. ARDS patient is treated in a hospital emergency ward. Common treatments is artificial ventilation and curing the underlying cause of ARDS. ARDS can complicate other disease conditions such as respiratory failure, pneumonia, pulmonary embolism, multiple organ failure. Cause ARDS causes are, Infection  Presence of infection in the lung area causing swelling, breathing difficulty and muscle spasm in lungs. It can further increase in ARDS sign and symptoms. Inhalation of harmful substances  Inhalation of harmful substances from air pollution, dust, and foam can increase the chance of obstruction in the lungs. This obstruction further ca...
