Thought it was anemia, but it turned out to be colon cancer? If there are 5 kinds of abnormalities in anemia, it may be a signal that cancer is coming

A Hua, 45, is a dishwasher in a restaurant. She usually squats to wash dishes, and her feet go numb for a while after each wash.

But when she got up, she suddenly felt dizzy, her eyes darkened, and she almost fell down . Fortunately, the worker next to her helped her to stand up.

Ah Hua suspected that it was anemia, so she bought red dates and brown sugar after get off work and went home to soak in water, but after eating for a while, it had no effect. Later, she went to a nearby clinic to prescribe medicine. However, after continuous treatment for more than a year, there was no improvement, so I went to the hospital for examination.

As a result, it turned out to be bowel cancer, and it was a severe anemia. The doctor pointed out that Ah Hua's anemia was caused by bowel cancer, so other treatment methods were ineffective. She waited for the symptoms, but she didn't understand and didn't take it seriously, which led to the delay of the disease.

1. Anemia that cannot be cured for a long time is actually colon cancer, why?

About 5% of colorectal cancer patients go to the hospital due to anemia that cannot be cured for a long time. Many patients have no symptoms of bowel cancer, so why does bowel cancer cause anemia?

First of all, after the occurrence of colorectal cancer, the mucosa on the surface of the cancerous tumor may erode and bleed, which may cause chronic blood loss and easily lead to anemia.

The proliferation and growth of colon cancer requires a large amount of nutrients, which may lead to excessive consumption of hematopoietic raw materials, thereby inducing anemia. In addition, after the metastasis of advanced colorectal cancer, the hematopoietic system may be destroyed, resulting in a decrease in the hematopoietic reserve function of the bone marrow, and anemia may also be caused.

Colorectal cancer with anemia as the first symptom mostly occurs in the right colon .

In addition to anemia, right-sided colon cancer may be accompanied by symptoms such as unusual weight loss, fatigue, abdominal mass, abdominal pain, and persistent low-grade fever . Anemia caused by colon cancer is generally common among middle-aged and elderly people. Most of these people are relatively obese and prefer a high-protein and high-fat diet.

2. Dizziness and dark eyes when standing after squatting for a long time, is it anemia?

Sometimes after squatting on the toilet or doing other things for a long time, we may experience dizziness and dark eyes. Is this caused by anemia?

The phenomenon of black eyes after getting up suddenly, also known as amaurosis transient, refers to the sudden blackness in front of your eyes, you can't see clearly what is in front of you, and you may also have symptoms such as tinnitus and dizziness. It can be relieved on its own. This situation is actually related to a variety of factors.

1. Orthostatic hypotension

This is because when the squatting position is suddenly changed to the standing position, the blood in the head, chest and abdomen rapidly flows to the waist, legs, etc. due to gravity, resulting in temporary ischemia of the head, causing temporary cerebral ischemia, retinal blood Temporary hallucinations may occur after the supply is reduced.

2. Cardiovascular disease

In patients with cardiovascular diseases such as arrhythmia, myocardial infarction, and cardiogenic hypotension, the blood output of the heart may be disturbed, resulting in abnormal blood supply to the whole body, resulting in sudden blackening of the eyes.

3. Hypoglycemia, anemia

Conditions such as anemia or low blood sugar may also cause sudden dizziness and dark eyes, but this dizziness may occur at any time.

4. Cervical spondylosis

Bowing your head for a long time may cause cervical spondylosis and may also cause dizziness.

The common anemias are mainly iron-deficiency anemia, such as insufficient iron intake in infants, lactating women, and pregnant women; iron absorption after subtotal gastrectomy; long-term hemoptysis, gastrointestinal blood loss, menstruation Excessive iron loss caused by too much, etc., may cause iron deficiency anemia.

Fatigue , shortness of breath, pale skin, dry skin, brittle nails, pica, repeated infections , etc., may all be caused by iron deficiency anemia.

3. Red dates, brown sugar... In fact, they do not nourish blood!

Many people may buy some red dates, brown sugar, and donkey-hide gelatin to supplement their blood after they have anemia. In fact, this is not reliable.

Red dates, brown sugar, donkey-hide gelatin and other foods do not actually replenish blood. It is not red food that can replenish blood. The color of food is related to pigment, and pigment does not contain iron. In comparison, the iron content of plant food is far less than that of animal food. .

It is these three foods that can really nourish blood.

1. Animal liver

Pig liver and other animal livers not only have a high iron content, but also have a high absorption and utilization rate. However, due to the high vitamin A content in pig liver, eating too much may lead to fetal malformations. It is recommended that pregnant women eat less animal liver.

2. Red meat

Red meats such as beef, pork, and mutton are also rich in hemoglobin and iron, which can be eaten appropriately. However, eating too much red meat may increase the risk of cancer, so you must control the amount you eat.

3. Animal blood

The heme iron content in animal blood is very high, the absorption rate is relatively high, and the fat content is not high, so it is a good blood supplement.

In addition to anemia caused by insufficient nutrition, it may also be an early warning of disease or cancer. We must be alert to anemia that cannot be cured for a long time, which may be a distress signal from colon cancer.

Usually, blood supplementation cannot rely on eating red dates, red beans, donkey-hide gelatin and other foods. To supplement blood, you can properly eat animal foods such as red meat, animal liver, and animal blood, and ensure a balanced and comprehensive diet.
