"How to eliminate lipomas?"

If you want to eliminate a lipoma, it generally requires surgical removal of the lipoma in its entirety. Lipomas are more likely to occur in subcutaneous fat or within muscle tissue. For small, asymptomatic lipomas, surgery is usually not necessary; however, if the lipoma enlarges, causes local compression symptoms, local pain, or if there is a significant increase in size in a short period, surgical removal can be considered, and most can be removed under local anesthesia. If the lipoma is on the back, due to prolonged compression, the difficulty of the surgery may be slightly increased.

Is the risk of tetanus high?

Tetanus occurs infrequently, but once it appears, the condition can be very severe and may lead to death if not treated promptly. Tetanus infection is mainly caused by infection with the tetanus bacillus. The tetanus bacillus is an anaerobic bacterium that exists everywhere in nature. If the wound is very deep with a small surface area, and the conditions inside the wound become anaerobic, if the tetanus bacilli inside the wound are not thoroughly cleaned, it could lead to the rapid reproduction of the tetanus bacilli, releasing tetanus toxin and causing a tetanus infection in the patient.

Can getting ear piercings lead to tetanus?

Piercing ears generally does not result in a tetanus infection. Since the wounds from ear piercings are relatively small, they basically reach aerobic conditions. Tetanus bacillus are anaerobic bacteria and generally do not proliferate in an aerobic environment. In an anaerobic environment, however, tetanus bacillus can proliferate extensively, which is when a patient might show symptoms of tetanus. However, the specific condition of the patient's ears must also be considered. If the patient’s earlobes are very thick, the small external opening from the piercing might create an anaerobic environment within the middle of the earlobe. If tetanus bacillus colonizes inside the wound, it may lead to extensive proliferation of the bacteria.

What should not be eaten with lipoma?

Lipomas are considered benign lesions, primarily caused by abnormal proliferation of subcutaneous fat. They form lumps in adipose tissue. If a patient is clearly diagnosed with a lipoma, it is generally recommended to adhere to a light diet, consuming less food that is high in fats or proteins. It is also advised to engage in more physical activity. Through appropriate exercise, it can effectively reduce subcutaneous adipose tissue, which can lead to weight loss. It is not recommended to eat fatty meats, protein-rich foods, seafood, and the like.

How deep is a tetanus wound?

There is no clear boundary concerning how deep a wound needs to be to carry a risk of tetanus; mainly, it depends on whether the conditions allow for anaerobic bacteria to thrive. Particularly, wounds that are very small on the surface but deep can lead to substantial proliferation of tetanus bacilli. A common example is a foot wound caused by stepping on a nail, where the exterior opening of the wound is small, but it is deep inside, and the nail surface may be rusty and also carry a large amount of tetanus bacilli. If the wound is not promptly and thoroughly cleaned, it can lead to massive growth of tetanus bacilli, resulting in the onset of severe illness in the patient.

Do lipomas hurt when pressed?

For most lipomas, there is no pain when pressed. Lipomas are formed due to excessive proliferation of subcutaneous fat, with clear boundaries and very good mobility, and there is no pain upon pressing. If the lipoma is small or there are multiple lipomas, there is no need for excessive attention or surgical treatment in everyday life. Of course, excessive massaging or rubbing should be avoided. If pain occurs when pressing the lipoma, or if the lipoma is relatively large and grows significantly in a short period, surgical removal should be considered. Generally, the lipoma can be completely removed under local anesthesia.

Is it necessary to get a tetanus shot?

Getting a tetanus shot is very necessary if a patient has had an injury or has wounds on the body. Without a tetanus shot, there might be a risk of tetanus infection. The main reason is due to the presence of tetanus bacillus spores in the natural environment, which could colonize within the wound if it's exposed. This can potentially lead to a tetanus infection. Severe cases can present with symptoms such as opisthotonos, breathing difficulties, suffocation, and could even lead to death. The tetanus shot involves injecting tetanus antitoxin into the patient's body, which is a form of passive immunity and can prevent some symptoms of tetanus infection.

Can lipomas be massaged?

Lipomas should not be massaged. They form from abnormal hyperplasia in the subcutaneous fat tissue of the patient, presenting as localized nodules or lumps with clear boundaries and usually painless when pressed. Lipomas can be solitary or multiple. If the lipoma is small, close follow-up is sufficient; massaging or local stimulation is generally not recommended. Massaging or stimulating the area can potentially lead to an increase in the size of the lipoma, and it may provoke pain and other complications. In severe cases, it can cause the lipoma to become malignant.

How to eliminate hypertrophic scars?

For the elimination of hypertrophic scars, one can apply anti-scarring ointment to the surface early after surgery. If the patient indeed has a scarring constitution, at the end of the surgery, it is advisable to inject medications into the subcutaneous area or within the wound tissue to prevent excessive or abnormal scar proliferation. If necessary, radiotherapy can be applied; under the effect of X-rays, it can effectively prevent the abnormal proliferation of scar tissue and the abnormal and excessive growth of fibroblasts. If there is already hypertrophic scarring, one might consider excising the hypertrophied scar tissue and re-suturing the wound.

How to press back an umbilical hernia?

Umbilical hernias are generally more common in newborns, primarily because the umbilical ring has not yet completely closed. In children, lumps appear in the navel area when they cry or when abdominal pressure increases. To address an umbilical hernia, first massage the area around the belly button, then gently return the hernial sac to the abdominal cavity with both hands. After returning the hernia, secure it externally with a hernia belt. This can effectively prevent the recurrence of the umbilical hernia. Typically, through conservative treatment, which involves this method of binding for about one to two months, the patient’s umbilical hernia can heal on its own.
