Title: What could cause sudden changes in body temperature not related to the weather?
Post by: cassandra_326 on 09/01/2012 15:11:34
This past week I have been experiencing quite significant changes in my temperature. I have been monitoring it several times a day and have noticed that as long as I'm covered up (comforter, socks, sweatpants), than my temperature will generally stay between 97 and 98.3, but as soon as I get up and walk around my temperature will drop. This has gotten worse the last few days and this morning it got down to 95.3 about five minutes after I got out of bed (it was 97.4 right before I got out of bed). Yesterday the drops were only in the 96 degree area. Other symptoms, I am horribly tired, been bruising very easily, headache, night sweats and I get light headed often when I stand quickly. My normal body temperature was around 99 prior to this past week or so. I haven't taken my temperature in about 6 months though so this may have been happening earlier but I only recently noticed the other symptoms so.... I have had a little bit of nasal stuffiness the past few weeks and am wondering if my symptoms could be explained by just being a little "under the weather"?

Oh and some additional facts about me. I am a 24 year old female and take zoloft (200 mg), adderall (20ir 3x daily) and microgestin (birth control pill).

Spontaneous bruising is something that you should report to your doctor.

An immune response, (to infection / self / medication / foodstuff), can produce fever and chills (+fatigue + headache).

Spontaneous bruising can be caused by immune response, (e.g. vasculitis or immune-mediated coagulation disorder).

As your symptoms have persisted for more than a week then you should definitely consult your doctor about them.


If the “nasal stuffiness” includes nasal bleeding / blood-streaked mucus you should mention that to your doctor, even if the volume of blood involved was tiny.

Purpura ( is not caused by trauma, as are contusions, but by a variety of medical diseases, disorders and conditions including:

    Autoimmune diseases, such as lupus and rheumatoid arthritis

    Certain infectious diseases, such as meningitis, mononucleosis and measles

    Certain medications, such as aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, antihistamines, and blood thinners

    Insect bites


    Thrombocytopenia (low platelet count that causes problems with clotting)

    Vasculitis (inflammation of blood vessels)

Since you mentioned dizziness, changes in blood pressure can effect body temperature as well. Chills and sweating are associated with infections. I dont know the side effects of zoloft, but the hypothalamus regulates both mood and body temperature. Body temperature changes throughout the menstrual cycle, but not suddenly. I would be more concerned about the bruising. Its time to ask your doctor and at least have some routine blood tests.

Your body temperature can vary a couple of degrees normally, going from a warm bed to a cold house, or heading outside for a chilly bicycle ride.

Likewise, in the summer, when working hard, it can increase slightly.

Most serious infectious diseases such as meningococcus cause an increase in body temperature, so a slightly lower than normal temperature is a good sign.

I would encourage taking a pregnancy test if you have been sexually active during the last few months, even if you have been taking "the pill".

A physician visit would be encouraged.
