The link between obesity & stomach cancer

Obese would be titled for people whose body mass index is greater than 30. Excess fat and being overweight can be termed as obesity. This excess of body fat can be harmful and cause a lot of health issues and complications as well. 


The most common causes of obesity would be too much intake of food, alcohol, certain medications, lack of sleep, and no physical activity. These could cause certain types of cancer, and women are at higher risk of developing cancers of the endometrium, breast, colon, kidney, and gallbladder.

Obesity & stomach cancer

Stomach cancer is considered to be a malignant ulcer in the lining of the stomach. It is also known as gastric cancer. One of the causes that leads to stomach cancer is the excess of fat or obesity. The chronic inflammation associated with obesity increases the risk of gastric cancer. Obesity can produce more insulin and leptin, which would lead to increased cell proliferation, promoting the growth of cancerous cells. People who are obese are more prone to develop H. pylori or Helicobacter pylori infection, which is considered to be a risk factor for peptic and gastric cancer. And the abdominal fat can be a risk factor as it produces oesophageal reflux, which in turn causes gastric cancer. 

Medical care 

Obesity would become a hindrance to a lot of treatments or treatment protocols. It affects the dosage of chemotherapy. Obesity is just one factor, but it layers on top of all the other factors that would trigger stomach cancer. A healthy lifestyle and diet can be the best way to prevent cancer, plus lowering the risk of obesity and other complications. 

Gastroscopy, CT scan, and upper GI series would be used to diagnose stomach cancer. Gastric surgery can be performed to help treat obesity when other treatments and methods fail. Usually, gastric cancer would require surgery in the form of partial or total gastrectomy or bypass.

 Stomach Cancer

Even though there are various methods and treatments for gastric cancer, it is better to prevent the issue initially. It is always suggested to maintain a proper diet to stay fit and healthy.

What To Know About Chronic Pancreatitis?

The pancreas is the most hardworking organ in the human body. It plays a significant role in your digestion process. It makes enzymes that help your digestive process and insulin to keep your blood sugar levels under control. Any inflammation, fibrosis, or scarring of the pancreas will develop a condition called pancreatitis. 

What is pancreatitis?

Pancreatitis is a disease in which the pancreas becomes inflamed or damaged. This is when the digestive enzymes are activated before they are released into the small intestine and begin attacking the pancreas. Pancreatitis can become a chronic problem. Treatment for this condition varies depending on whether your pancreatitis is acute or chronic. 

Acute pancreatitis is a sudden inflammation of your pancreas, which can be very painful. You may have nausea, vomiting, and fever. If acute pancreatitis slowly gets worse,It may lead to chronic pancreatitis.

What is chronic pancreatitis?

Chronic pancreatitis is an irreversible and progressive disorder of the pancreas caused by an inflammation that constantly occurs over the long haul. Chronic pancreatitis can create permanent damage to the pancreas. Scar tissue develops from this long-term inflammation.

What causes chronic pancreatitis?

If you have chronic pancreatitis, the digestive enzymes that would normally travel by tubes inside your pancreas and empty into your upper intestine, become trapped inside your pancreas, this causes pain and scarring. The trapped enzymes slowly destroy your pancreas.

The most common cause of chronic pancreatitis is drinking too much alcohol over many years. 

 Other causes include:
  • An attack of acute pancreatitis that damages your pancreatic ducts
  • A blockage of the main pancreatic duct caused by cancer 
  • Certain autoimmune disorders
  • Cystic fibrosis
  • Hereditary diseases of the pancreas
  • Smoking
  • Unknown cause in some cases 

How to diagnose?

If pancreatitis is suspected, It is best diagnosed with tests that can evaluate the structure of the pancreas via radiography. Your doctor will likely use a combination of blood tests and imaging studies to make a diagnosis. 

Computed tomography is the best imaging modality for diagnosis. Your doctor may recommend a variety of diagnostic tests such as; Transabdominal ultrasound, Endoscopic ultrasound, and Magnetic resonance cholangiopancreatography (MRCP).

How is chronic pancreatitis treated?

Day-to-day treatment includes: 
  • Pain medicine
  • Pancreatic enzyme supplements with every meal
  • Insulin, if you develop diabetes
  • Vitamin supplements, if needed
For acute pancreatitis or a flare-up, you may need to stay in the hospital for treatment. Your exact treatment will depend on the cause of your chronic pancreatitis, how severe the symptoms are, and your physical condition. 

Acute treatments may include:
  • Feeding through a tube through the nose into the stomach
  • Diet
  • IV fluids
  • Pain medicines
  • Surgery 

You can control pancreatitis with a healthy lifestyle and medical treatment when necessary. Organizations such as the SIMS hospital can provide resources and support to help you live a full and healthy life with pancreatitis.

However, if any of your symptoms reappear, speak with your doctor as soon as possible.

The recovery period after hernia surgery:

After hernia repair surgery, the patient is kept in the postanesthesia care unit (PACU) for close monitoring. They will remain there until they are stable. The amount of time spent in the PACU depends on the patient's progress and on the type of anesthesia they had received.

Post-Operative Care And Recovery

  • Immediately after surgery: After leaving the post-anesthesia unit, the patient is shifted to the daycare department. The patient is discharged after a few hours.
  • There will be negligible pain at the operated site because of pre-emptive analgesia and TAP block.

First Week Do’s And Don’ts

Following are some of the tips that can help to prevent infection, promote healing, and avoid weight gain.

  • Depending on wound healing, you can take the patient to shower within a day or two.
  • Make sure the patient does not strain abdominal muscles while walking. However, an ideal level of strain can improve circulation.
  • Plan a diet rich in fruits, vegetables, and fiber along with a lot of fluids. This keeps constipation at bay. If the patient is straining that results due to inactivity seek immediate doctor's help. Physicians may prescribe laxatives or stool softeners to avoid

Tips For A Speedy Recovery

  • Ensure that a relative or family stays with the patient after surgery. This will help the patient as he/she is physically restricted to do many things.
  • Keep a pillow next to the patient so that in case he/she needs to cough, sneeze, or vomit, he/she can press it against the abdomen. This helps to prevent excessive strain on abdominal muscles.
  • Reduce using stairs as it may be physically exhausting to climb up and down.
  • Be aware of all the potential complications post-surgery. This enables you to call your doctor immediately if you notice any.
  • Be consistent in all your follow-ups with your doctor for your safety and the success of your surgery.

Most doctors ask their patients to return in about a week for a follow-up visit. At this time, all stitches will be removed.

Why Esophageal Surgery Is Done?

An esophagectomy is a surgical procedure that is commonly used to treat esophageal cancer. Depending on the size and extent of a patient’s tumor, the surgery can be adjusted to remove a part or all of the esophagus, then rebuild a way from a section of the patient’s stomach or large intestine for the food to pass.
esophageal cancer surgery in india

There are two ways that an esophagectomy can be performed: as a traditional (open) surgery and minimally invasive (laparoscopic) procedure. The specific approach that a surgeon selects for a patient will depend on several factors, such as:

•    The size of a tumor
•    The location and accessibility of a tumor
•    The patient’s overall health

Compared to a traditional esophagectomy, a minimally invasive esophagectomy can result in a shorter hospital stay and a shorter overall recovery period, as well as less scarring and a reduced likelihood of complications. However, each patient needs to discuss the potential advantages and outcomes of each approach with an experienced surgical oncologist.

Why is it done?


Esophagectomy is done as a treatment for esophageal cancer; Barrett’s esophagus with high-grade dysplasia (pre-cancerous cells); or for end-stage achalasia (failure of the muscles of the esophagus to relax making it hard to swallow).

How is it done?


esophageal cancer surgery india

There are a few ways to do an esophagectomy. You may have an incision in your neck, abdomen, and/or chest. If it can be done in a minimally invasive fashion with a laparoscope (a small camera) you will have five to seven tiny incisions in your chest and/or abdomen. Your surgeon will discuss with you how the operation will be done and where the incisions will most likely be made.

Most patients can be discharged from the hospital within 7 days of the surgery.
