Bad odor is often a sign of an underlying condition and not a disease in itself. This is why it is important to identify the root cause of bad odor so that the underlying condition responsible for it can be detected and treated.
Moreover, a bad odor can create a sense of embarrassment for people of all ages and genders. It can make them feel more anxious and stressed out, especially when they have to meet new people.
Bad odor can also affect the overall impression created by a person as it is commonly perceived as the lack of personal hygiene by others. This can prevent the person from achieving success in his or her career and even affect their personal relationships. 
If not managed in an appropriate and timely manner, bad body odor may reduce the self-esteem and self-confidence of a person putting him or her at risk of depression.
This marks the need to address body odor and adopt healthier ways to avoid it. It is important to identify the root cause of body odor and seek appropriate treatment to derive long-lasting results.
As discussed earlier, some medical conditions can affect how much a person sweats and the odor the sweat produces.
Bad body odor could be a sign of a serious condition. Hence, it is important to see your doctor and get yourself checked so that the exact cause of this symptom can be detected.
A person should visit a doctor if the increase in sweating usually occurs at night or when the bouts of sweating occur irregularly and at excessive levels.
Experiencing cold sweats or sudden changes in the sweating pattern are also some reasons you should visit a doctor to find the underlying cause and avoid serious complications.
Can diet and exercise help to reduce body odor?
Some foods are known to contribute to unpleasant body odor.
For example, garlic and onions have an aroma that may come out through the pores of your skin when you sweat causing body odor. Alcohol and caffeinated beverages can also cause you to sweat more.
Hence, it is advisable to watch out your diet and find foods that could be responsible for causing bad odor.
Similarly, exercise may contribute to body odor by increasing how much you sweat. Increasing your water intake before and after your workout sessions may help to reduce body odor in this case.
