Warning signs to look out for if you are over 40

There are many benefits to aging, which usually include an increase in confidence and becoming more comfortable with who you are and what you want. However, the downside to aging is that the older you get, the less functional your body becomes, and many issues can start to appear.
Take a look through the following gallery to discover warning signs to look out for if you are over 40.
Loss of smell

While the loss of smell alone is highly disturbing, it can also lead to memory loss and be an early sign of Alzheimer's and dementia.
Abdominal bloating

While the causes may often be benign, abdominal bloating can also be an early warning sign of ovarian cancer.
Unexpected weight loss

If you start losing weight unintentionally, it could be a sign of type 2 diabetes. Those aged 45-64 are most at risk of developing it.
Nausea

There can be a huge number of reasons why a person may feel nauseous. But nausea and stomach pain can be a warning sign of heart disease.
Neck stiffness

While neck stiffness could just be caused by a bad night's sleep, it could also be a sign of polymyalgia rheumatica, which is an inflammatory disease.
Fatigue

It's natural to feel fatigue, because our bodies need sleep. However, if it becomes chronic, see your doctor, as it could be linked to vitamin D deficiency, or even heart disease.
Change of humor

If someone suddenly develops a much darker sense of humor, it could be a sign of frontotemporal dementia, or Alzheimer's.
Knee pain

If you experience pain around the joint of your knee, this can be an indication of early arthritis or degeneration.
Coughing

There are a huge number of reasons why someone may develop a cough, but one of them is due to mesothelioma, which can occur when people have been exposed to asbestos.
Red face

While the visible symptoms of rosacea aren't dangerous, they may cause you embarrassment. If you also experience high blood pressure, and excessive sweating, it could be a hormonal issue.
Stomach ache

While a stomach ache could be symptomatic of an allergy or intolerance, it can also be a sign of inflammatory bowel disease, or even pancreatic cancer.
Calf pain

Some calf pain can come from pulling a muscle. However, it could be a sign of deep vein thrombosis, which can lead to a potentially lethal pulmonary embolism.
Blood in urine

Blood in your urine can be indicative of an infection, kidney stones, or even bladder or kidney cancer.
Erectile dysfunction

There are a huge number of factors that can influence ED, including age, psychological issues, and lifestyle. However, it could also indicate heart disease.
Itchy skin

Many things can cause itchy skin, such as eczema, or even just being dehydrated. However, it could also be indicative of liver disease.
Forgetfulness

A certain element of forgetfulness is a natural consequence of aging. However, when it interferes with your normal routine, it could be a sign of dementia.
