The signs are similar to normal pregnancy and you would be well acquainted with them if you have given birth earlier. If your internal health condition is absolutely fine, then getting pregnant is absolutely possible at this age. When you have planned to conceive, you would come to know about your pregnancy from the following symptoms.

Missed Period
Menopause usually doesn't take place at the age of 40. If you are having periods regularly every month, then this time you will miss your periods. Women usually wait for for this sign of a skipped period in order to confirm that they are pregnant. Carry out the pregnancy test at home and feel happy to see the strip turning pink. The other symptoms will follow automatically.

Morning Sickness
Feeling nauseated, and experiencing dizziness after waking up are early signs of being pregnant. Sometimes they become so intense that you will have to restrict yourself from working for the time being. A tendency to vomit immediately after eating or on an empty stomach is common. You will also feel sleepy and lethargic. To combat all these, you must take sufficient rest.

Appetite Changes
Pregnancy is the time during which mood swings become rampant. This leads to loss of appetite. You will be astonished to see yourself refraining away from your favorite dishes while gorging on foods that you would never eat. Incredible hunger pangs for specific dishes would drive you crazy. There will be a drastic fluctuation in your appetite and therefore you should try every possible means to satiate your hunger.

Physical Discomfort
Experiencing physical discomfort is something inevitable. Cramps in back, legs and abdomen are common and you have to bear with them. In extreme conditions, you can take pain killers under a doctor's suggestion to get relief from the pain. This happens due certain internal changes taking place inside body for accommodating your baby.

Weight Gain
With every passing day, you will feel heaviness in your body. Weight gain during pregnancy is unavoidable. Your appetite increases, you eat more, as a result of which you put on weight. Feeling bloated due to retention of water in legs and stomach are also natural. Swelling in face and hands are common observations during pregnancy.

Frequent Urination
You will feel frequent urgency to pee when you are pregnant. This happens because the volume of blood present inside your body rises dramatically and a lot of fluid needs to get dispelled from your bladder. Moreover, you are advised to drink a lot of fluids in the form of water and fresh juices, that further steps up the rate of urination.

These were the most common signs of pregnancy over 40. Women suffering from health complications like thyroid gland disorders, genetic problems, obesity, ovarian cysts and hormonal problems must take a doctor's advice before giving themselves a chance to conceive. The risks of pregnancy over 40 are mainly concerned with miscarriage, placenta previa and birth defects in the newborn child. All these are major concerns that should be taken care of. If you are unable to conceive after 40, then you must resort to artificial techniques of getting pregnant.

The signs explained in the aforementioned content will be experienced by you in early days and with passage of time you will be experiencing other types of physical changes. Thus, you should be prepared to endure the series of emotional and physical changes taking place throughout your gestation period. Last but not the least, I should say that it's a different experience altogether and you must stay happy and energetic for healthy development of your baby.

Why Body Temperature Rises during Fever

The Hypothalamus present in the brain is the area that regulates the temperature of the human body, and when some agents known as Pyrogens enter the brain the hypothalamus causes the temperature to rise. These pyrogens reach the brain through the bloodstream of the body, so it is only a matter of time before they complete their route. Medical studies also show that certain microorganisms cannot survive in higher temperatures, and this is another reason why the body temperature rises. Hence this is the most natural kind of immune and defense mechanism that the human body undertakes in order to protect itself from the threat of any external agent.

The normal body temperature of a human bring should be 98 - 100° Fahrenheit (or 36.5 - 37.5° Celsius). Any person who has a temperature that is above this figure is said to be suffering from a high fever. It is necessary to curb a fever and bring the body temperature down because a very high temperature can cause permanent damage to the brain as well. This has led to an interesting debate in many medical quarters about whether a fever should be treated immediately, or should it be allowed to run its natural course and come down on its own.

Stages and Types of Fever

In order to achieve body temperature regulation it is important for doctors and individuals to know about the various types of fevers that they can contract. When a person realizes that they have a high body temperature they need to know the various stages of the fever as well. The fever also causes the blood vessels that are closer to the skin to contract and this results in the sensation of cold and chills and causes the person to shiver (since this action prevents heat loss). Other symptoms at this stage include headaches and loss of appetite and this stage is known as the invasion period. In the next stage the individual starts feeling very thirsty, and their heart rate and blood pressure rise to high levels. Even the respiration becomes faster and the person experiences a feeling of extreme hotness and flushness. The last stage occurs when the fever starts falling and the body temperature falls, and the individual perspires a lot.

One of the types of fever is continued fever and this is an instance when the fever just does not fall for prolonged periods of time. This is usually the most dangerous kind of fever since the prolonged state can lead to convulsions and deliriousness in a patient. The other type is called relapsing fever, and this happens when the person contracts a fever many days after the original fever struck. This is a sign that the disease has not been banished yet, and has only been dormant for the interim period. The last type is known as intermittent fever and this is a scenario when the fever comes and goes from time to time. This is perhaps the most commonly seen and least dangerous type of fever.

In most cases it is very easy for a doctor to find the cause of a fever. Once it has been located, treating this factor and lowering the high body temperature during fever is just a matter of time. There are hundreds of different infections that can cause the body to suffer from a fever, but even though the body temperature rises and leads to a fever as a defense mechanism, it can get quite uncomfortable sometimes.
