pig influenza / swine flu

Pigs’ physical makeup allows them to contract—and to spread—influenza viruses to and from other species, such as humans and birds. Due to their susceptibility to influenza virus infections from other species, pigs can also serve as “mixing vessel hosts” that can produce new influenza virus strains that could pose a risk to human health.

Potential Symptoms:

1. fever
2. lethargy
3. lack of appetite
4. coughing
5. runny nose
6. sore throat
7. nausea
8. vomiting
9. diarrhea

It is important to remember that many of the signs and symptoms of swine flu are similar to those of regular flu. They may also stem from a variety of other conditions and illnesses. In other words, if you're feeling sick, don't immediately panic and assume the worst.

The word "IF"

"If you're sick, it's very important that people stay at home. If your children are sick, have a fever and flu-like illness, they shouldn't go to school. And if you're ill, you shouldn't get on an airplane or another public transport to travel. Those things are part of personal responsibility in trying to reduce the impact. "

If you're feeling ill, it's helpful to be aware of the symptoms of swine flu so that you can alert your doctor. They are similar to those of ordinary human flu: fever, cough, sore throat, body aches, chills, headache, and fatigue. In some cases, vomiting and diahrrea have also been reported.

Recommendations to avoid influenza

In order to prevent the transmission of influenza, the Secretary of health in Mexico indicated to:
1. Avoid crowded places
2. Avoid close spaces
3. Avoid salutations with the hand and kisses
4. Wear tissues to cover mouth and nose
5. Go to the doctor at the minimal sign of flu
6. Enhance your immunologic system
7. Wash your hands with soap and water frequently
8. Sneeze in the arm, under the elbow, instead of doing it in the hand
9. Try to stay at home.
10. Never self-medicate
11. Eat fruit and do not drink alcohol nor smoke
12. Avoid sick people

What is obesity?

The definition of obesity varies depending on what one reads, but in general, it is a chronic condition defined by an excess amount body fat.

A certain amount of body fat is necessary for storing energy, heat insulation, shock absorption, and other functions. The normal amount of body fat (expressed as percentage of body fat) is between 25%-30% in women and 18%-23% in men. Women with over 30% body fat and men with over 25% body fat are considered obese.
The calculation of body mass index (BMI) has also been used in the definition of obesity. The body mass index (BMI) equals a person's weight in kilograms (kg) divided by their height in meters (m) squared. Since BMI describes body weight relative to height, it is strongly correlated with total body fat content in adults. "Obesity" is defined as a BMI of 30 and above. You can calculate your BMI using my widget down below.

What Causes Overweight and Obesity?

For most people, overweight and obesity are caused by not having energy balance. Weight is balanced by the amount of energy or calories you get from food and drinks (this is called energy IN) equaling the energy your body uses for things like breathing, digesting, and being physically active (this is called energy OUT).
Energy balance means that your energy IN equals your energy OUT. To maintain a healthy weight, your energy IN and OUT don’t have to balance exactly every day. It’s the balance over time that helps you maintain a healthy weight.
• The same amount of energy IN and energy OUT over time = weight stays the same
• More IN than OUT over time = weight gain
• More OUT than IN over time = weight loss
Overweight and obesity happen over time when you take in more calories than you use.

Is there other causes?

Yes, i'll show you all the causes right away.

Physical Inactivity

There are many reasons for this. One reason is that many people spend hours in front of TVs and computers doing work, schoolwork, and leisure activities. In fact, more than 2 hours a day of regular TV viewing time has been linked to overweight and obesity.
People who are inactive are more likely to gain weight because they don’t burn up the calories that they take in from food and drinks. An inactive lifestyle also raises your risk for heart disease, high blood pressure, diabetes, colon cancer, and other health problems.

Genes and Family History

Because families also share food and physical activity habits, there is a link between genes and the environment. Children adopt the habits of their parents. So, a child with overweight parents who eat high-calorie foods and are inactive will likely become overweight like the parents. On the other hand, if a family adopts healthful food and physical activity habits, the child’s chance of being overweight or obese is reduced.

Health Conditions

Sometimes hormone problems cause overweight and obesity.
Certain medicines such as corticosteroids and other related medicines may cause you to gain weight. These medicines can slow the rate at which your body burns calories, increase your appetite which can lead to weight gain.

Emotional Factors
Some people eat more than usual when they are bored, angry, or stressed. Over time, overeating will lead to weight gain and may cause overweight or obesity.


Some people gain weight when they stop smoking. One reason is that food often tastes and smells better. Another reason is because nicotine raises the rate at which your body burns calories, so you burn fewer calories when you stop smoking. However, smoking is a serious health risk, and quitting is more important than possible weight gain.


As you get older, you tend to lose muscle, especially if you’re less active. Muscle loss can slow down the rate at which your body burns calories. If you don’t reduce your calorie intake as you get older, you may gain weight. Midlife weight gain in women is mainly due to aging and lifestyle, but menopause also plays a role. Many women gain around 5 pounds during menopause and have more fat around the waist than they did before.


During pregnancy, women gain weight so that the baby gets proper nourishment and develops normally. After giving birth, some women find it hard to lose the weight. This may lead to overweight or obesity, especially after a few pregnancies.
