Unexplained weight loss
Unexplained weight loss is one of the most important symptoms not to ignore.
While gradual weight changes can happen with stress, lifestyle shifts or ageing, losing weight without trying (typically defined as more than 5 per cent of body weight) can signal an underlying medical issue that needs attention.
One of the most concerning causes of unexplained weight loss is cancer. Many cancers increase the body’s metabolic demands, meaning you burn more energy even at rest. Tumours can also alter appetite, digestion and nutrient absorption.
Hormonal disorders are another frequent cause. An overactive thyroid, known as hyperthyroidism, speeds up metabolism, causing the body to burn calories rapidly.
Digestive conditions can also interfere with the body’s ability to absorb nutrients.Unexplained weight loss may also be linked to metabolic conditions such as Type 2 Diabetes.
Because unexplained weight loss has many possible causes ranging from mild to serious it should never be dismissed.
Blood in stool
Blood in the stool is a symptom that should never be ignored.
While it can sometimes be caused by minor issues, it may also signal a more serious underlying condition. The colour, amount and frequency of the bleeding can provide important clues, but any unexplained blood in the stool should be assessed by a healthcare professional.
Bright red blood usually indicates bleeding from the lower part of the digestive tract, and one common cause is haemorrhoids. Darker blood, maroon-coloured stool, or black, tarry stool can suggest bleeding higher in the digestive tract. Black stool, sometimes described as sticky or foul-smelling, may indicate bleeding from the stomach or small intestine. This can occur with ulcers, inflammation or other digestive disorders.
One of the most important conditions to rule out is colorectal cancer.
Blood in the stool can be an early warning sign, particularly when accompanied by changes in bowel habits, unexplained weight loss, fatigue or abdominal discomfort. The amount of blood can vary widely. It may appear as streaks on toilet paper, mixed into stool, or present as black discolouration. Even small amounts should not be ignored and anyone experiencing blood in the stool should seek medical advice.
Persistent fatigue
Persistent fatigue is more than simply feeling tired after a busy week. It refers to ongoing exhaustion that doesn’t improve with rest and interferes with daily life.
While occasional tiredness is normal, fatigue that lasts for weeks especially when it’s unexplained can signal an underlying health issue that deserves attention.
One common cause of persistent fatigue is anaemia. Hormonal imbalances are another major contributor. Fatigue has also been linked to sleep disorders, Type 2 diabetes and chronic infections and inflammatory conditions.
