If you are an observant person, there is a high chance that you would have noticed a number of telltale signs and symptoms that precede the full blown illness.
You Have Low Appetite
If you’re coming down with gastroenteritis, you might have a sense of abdominal fullness that makes you lose your appetite. Not having an appetite or not enjoying foods you normally do could also signal that you’re on the brink of becoming ill with other kinds of infections, from a cold to strep throat.
You’re Mentally Exhausted
Do you feel irritable and don’t feel like jumping out of the bed even though you’re normally a morning exerciser? These signs could indicate that you’re coming down with an illness.
When you’re getting sick, there may be mild depression in that you don’t want to go out with your friends, you don’t want to go shopping, or do things you usually enjoy. All these things are clues that something is going wrong with your body.
You’ve Got Chills
There are certain illnesses that have an abrupt onset, where one minute you’re well, and then suddenly, you’re not. This is a common occurrence in flu and the symptoms typically include the rapid onset of chills and fatigue.
When you’re coming down with a cold, you’re more likely to feel mild fatigue or a scratchy throat; symptoms come on more slowly than for flu. Abrupt shaking, chills, and fever are usually signs of influenza or a bacterial infection that needs to be examined soon.
You’re Sweating Profusely
Sweating often accompanies fever and chills as part of everyday viral and bacterial infections. If you however notice that you’re soaking through your clothes and sheets (and you don’t normally have night sweats), you may want to visit your doctor.
Being drenched in sweat when you aren’t exercising, exerting energy, or battling an infection is a cause for concern. It could just be overactive sweat glands or menopause, but serious conditions that cause excessive sweating include cancer, heart disease, glucose control issues, lung disease, or medication side effects.
You Have Stomach Upset
Vague nausea, a bit of abdominal cramping, or a little diarrhoea are early signs that your stomach is not the way it ought to be. When someone has gastroenteritis (inflammation of the lining of the GI tract caused by bacteria or a virus), they might experience nausea, diarrhoea, abdominal pain, and vomiting.
A lot of people recover without treatment but be sure to drink fluids, since dehydration is common when you have this illness.
Your Body Temperature Is High
If you’re sneezing, have a headache, or feel sluggish, you may be wondering if you’re coming down with a cold or just suffering from allergies. When you have a cold you feel sick and generally have a low-grade temperature.
With allergic rhinitis and hay fever, you may feel congested and have repetitive sneezing, but if you tend to feel this way often, especially during the harmattan season and don’t have a temperature, it’s likely just seasonal allergies.
