Absolutely phenomenal doctor!!! I have visited other gastronomic doctors for throat difficulties but Dr. Daneshgar was better by far. He really made me a priority as a patient and scheduled tests way faster and more efficient than any other doctor. It's too bad yelp has only 5 stars because this doctor deserves 10!!
Dr Daneshgar is a pleasure. I had a colonoscopy with him and really felt nervous but i can't tell you how surpirzingly easy the procedure went. The entire staff is really friendly and the Dr is one of the best medical practicioners I have ever met.. Def recommend him!

What is capsule endoscopy?

Capsule endoscopy is a procedure that involves swallowing a small capsule the size of a large vitamin pill, and inside the pill, there is a tiny camera that takes pictures of the small intestine as it passes through. This allows your doctor to view and examine the images, providing useful information regarding your small intestine.

How do I know if I’m lactose intolerant?

Your doctor can determine if you’re lactose intolerant based on a breath test, which detects levels of hydrogen. If elevated levels of hydrogen are found, then it is indicative of an improper digestion of lactose, resulting in a lactose intolerance.

Heartburn can be treated in a number of ways, including medications, such as antacids and acid blockers, changes in diet or lifestyle, or surgery (in severe cases).

What is acid reflux?

Gastroesophageal reflux disease (GERD), commonly known as acid reflux, is a disease that develops when the valve between the esophagus and the stomach called the lower esophageal sphincter (LES), breaks down due to weakness or damage, resulting in stomach acid to move backward into the esophagus from the stomach.

Is a colonoscopy painful?

Colonoscopies are usually performed under sedation, which is administered by an anesthesiologist. Therefore, patients typically don’t remember the examination, as they are usually sleeping throughout the procedure due to sedation. However, sedation isn’t always necessary. If you choose not to be sedated, the procedure can be moderately uncomfortable, resulting in bloating, pressure, and cramping.

How do I check for colon cancer?

You can check for colon cancer by scheduling a colon cancer screening with a gastroenterologist in Thousand Oaks. Colon cancer screenings are extremely important, as they screen patients for colon cancer and polyps that can potentially lead to colon cancer.

What age should screen for colon cancer?

Men and women 40 years of age or older should be screened for colon cancer, at least every couple years (depending on the findings in previous colon cancer screenings). However, if you have a family history or colon cancer or adenomatous polyps, consult with a doctor about receiving a screening before age 40.

What is a gastroenterologist?

A gastroenterologist specializes in prevention, diagnosis, and treatment of the gastrointestinal tract and liver. If you have any symptoms of a digestive health disorder or need colon cancer screening, then you should see a gastroenterologist.

How often should I see a gastroenterologist?

We suggest seeing a gastroenterologist every couple years, especially for colon screenings, as these routine checkups save lives. While most doctors suggest colon cancer screening after 40, you can even start before then to ensure there are no signs of colon cancer or polyps.
