What is Colitis?

Posted on March 14, 2016 | 3 comments

Today many people are suffered by the Colitis in this day. I also have the Colitis and still I have to regulate foods and exercise for recovering my intestine. Today I want to discuss about the Colitis in this blog.

Before I start to talk about the Colitis, I want to explain about the colon. Colon is the part of the Large intestine inside our body. People can absorb water, nutrients, and other vitamin or elements inside this colon. Also waste products are removed as feces. However, this colon can be infected and causes Colitis.

Infectious Colitis

There are many bacteria in this colon. However, not all these bacteria are useful in the colon. Viruses and bacteria can cause colon infections by food poisoning or mutation. Also contaminated water can cause Infectious Colitis.

 

Ischemic Colitis

The large intestine is filled with many arteries. The reason is for absorbing nutrients into the blood from the colon. However these arteries can cause Ischemic Colitis. These arteries can be narrowed by disease, stress, or the twist of intestine. Therefore the blood can not transfer oxygen and nutrients into the blood. Finally, the colon will be inflamed.

These infections of Colitis can cause diarrhea by the bacteria and contaminated water or foods. Also the inflammation of the colon will cause pain, fever, and fatigue. The reason is that the nutrients and oxygen are limited by the less absorption from the intestine. Also Colitis causes joint swelling, skin inflammation, or the pain in the intestine. The bacteria and virus destroys the normal pattern of muscle contraction in the large intestine and less amount of water is remained in the intestine by the diarrhea. Therefore, the feces in the large intestine cause pain in the colons. Therefore, bleeding and injury in the colon are occurred.

Prevention

Most of the Colitis is caused by the bad food habit. Therefore, the patient should reduce to eat meat, alcohol, or other junk foods. Also the patient should quit smoking and trying to exercise and eat fibers and vegetables. Finally, the patient should avoid contaminated foods and do not have stress.

Is it possible to have sex in space?

Whenever we watch the movies like ‘Martian’ or ‘Interstellar,’ we want to know having sex in space will be possible or not. This is one of the most famous questions from the astronauts. Before understanding the scientific knowledge of gravity, we might think that we can have sex in space. However the answer for this question is no it is impossible to have sex in space. The reason is that the micro-gravity environment in space causes many problems. In this blog, I want to introduce the four main problems.

The first problem is with the regulation of blood flow. Low gravity affects the blood flow throughout the body unlike the way as on the Earth. Gravity normally helps our blood flow to reach the lower parts of our body on the Earth. However in space, blood rises to your head and chest first. Therefore it will be much more difficult for males to achieve an erection. As we learned from CAPS 390, erection is related primarily to blood flow and regulated by the relaxation and contraction. However, the blood flow is so slow to reach the lower part of our body. It is impossible to contract.

The second problem is sweat. This will be disgusting example if we have sex in space. Sweat tends to make many layers around the astronauts and making them sticky and wet. The reason is that the low gravity causes the sweat droplet do not fall to the ground and stick to the body. There is no pushing force like gravity; the droplets are only influenced by the adhesion force.

The third problem is that male testosterone levels decrease in space. This will diminish the sex hormones in space. NASA still could not discover why the testosterone levels decrease. However, when the astronauts return to the Earth, the testosterone levels reach to the normal state.

The last problem is with our heart and muscle. In space, our heart does not need to pump blood faster to the rest of our body. The reason is that the gravity does not push any blood flow to the lower part of body harder. Therefore, our hearts shrink when we are in space. Also our muscles become weaker because we do not use muscles to overcome the gravity. This is a huge problem when you have sex. The reason is that your heart rate suddenly increases and you breathe harder. Therefore, your body will become tired and muscles will decrease.

In the conclusion, through the micro-gravity issue, it is impossible to have a sex in space.
